 # Overview
-mxisd is a Federated Matrix Identity server for self-hosted Matrix infrastructures.
+mxisd is a Federated Matrix Identity server for self-hosted Matrix infrastructures with [enhanced features](#features).
+As an enhanced Identity service, it implements the [Matrix Identity service API](https://kamax.io/matrix/api/identity_service/unstable.html)
+and several [extra features](#features) that greatly enhance user experience within Matrix.
+It is the one stop shop for anything regarding Authentication, Directory and Identity management in Matrix built in a
+single coherent product.
   
-mxisd uses a cascading lookup model which performs lookup from a more authoritative to a less authoritative source, usually doing:
-- Local identity stores: LDAP, etc.
-- Federated identity stores: another Identity Server in charge of a specific domain, if applicable
-- Configured identity stores: another Identity Server specifically configured, if part of some sort of group trust
-- Root identity store: vector.im/matrix.org central Identity Servers
+mxisd is specifically designed to connect to an existing on-premise Identity store (AD/Samba/LDAP, SQL Database,
+Web services/app, etc.) and ease the integration of a Matrix infrastructure within an existing one.
 
-mxisd provides an alternative to [sydent](https://github.com/matrix-org/sydent), while still connecting to the vector.im and matrix.org Identity servers, 
-by implementing the [Matrix Identity Service specification](https://matrix.org/docs/spec/identity_service/unstable.html).
+The core principle of mxisd is to map between Matrix IDs and 3PIDs (Third-Party IDentifiers) for the Homeserver and its
+users. 3PIDs can be anything that uniquely and globally identify a user, like:
+- Email address
+- Phone number
+- Skype/Live ID
+- Twitter handle
+- Facebook ID
 
-mxisd only aims to support workflows that do NOT break federation or basic lookup processes of the Matrix ecosystem.
+If you are unfamiliar with the Identity vocabulary and concepts in Matrix, **please read this [introduction](docs/concepts.md)**.
 
 # Features
-- Single lookup of 3PID (E-mail, phone number, etc.) by the Matrix Client or Homeserver.
-- Bulk lookups when trying to find possible matches within contacts in Android and iOS clients.
-- Bind of 3PID by a Matrix user within a Matrix client - See [documentation](docs/sessions/3pid.md)
-- Support of invitation to rooms by e-mail with e-mail notification to invitee.
-- Authentication support in [synapse](https://github.com/matrix-org/synapse) via the [REST auth module](https://github.com/kamax-io/matrix-synapse-rest-auth).
+[Identity](docs/features/identity.md): As a [regular Matrix Identity service](https://kamax.io/matrix/api/identity_service/unstable.html#general-principles):
+- Search for people by 3PID using its own Identity stores
+  ([Spec](https://kamax.io/matrix/api/identity_service/unstable.html#association-lookup))
+- Invite people to rooms by 3PID using its own Identity stores, with notifications to the invitee (Email, SMS, etc.)
+  ([Spec](https://kamax.io/matrix/api/identity_service/unstable.html#post-matrix-identity-api-v1-store-invite))
+- Allow users to add 3PIDs to their settings/profile
+  ([Spec](https://kamax.io/matrix/api/identity_service/unstable.html#establishing-associations))
+- Register accounts on your Homeserver with 3PIDs
+  ([Spec](https://kamax.io/matrix/api/identity_service/unstable.html#establishing-associations))
 
-In the pipe:
-- Support to proxy 3PID bindings in user profile to the central Matrix.org servers
+As an enhanced Identity service:
+- [Federation](docs/features/federation.md): Use a recursive lookup mechanism when searching and inviting people by 3PID,
+  allowing to fetch data from:
+  - Own Identity store(s)
+  - Federated Identity servers, if applicable to the 3PID
+  - Arbitrary Identity servers
+  - Central Matrix Identity servers
+- [Session Control](docs/threepids/session/session.md): Extensive control of where 3PIDs are transmitted so they are not
+  leaked publicly by users
+- [Authentication](docs/features/authentication.md): Use your Identity stores to perform authentication in [synapse](https://github.com/matrix-org/synapse)
+  via the [REST password provider](https://github.com/kamax-io/matrix-synapse-rest-auth)
+- [Directory search](docs/features/directory.md) which allows you to search for users within your organisation,
+  even without prior contact within Matrix using arbitrary search terms
+- [Auto-fill of user profile](docs/features/authentication.md#profile-auto-fill) (Display name, 3PIDs)
+- [Bridge Integration](docs/features/bridge-integration.md): Automatically bridge users without a published Matrix ID
 
-# Lookup Process
-Default Lookup strategy will use a priority order and a configurable recursive/local type of request.
+# Use cases
+- Use your existing Identity stores, do not duplicate your users information
+- Auto-fill user profiles with relevant information
+- As an organisation, stay in control of your data so it is not published to other servers by default where they
+  currently **cannot be removed**
+- Users can directly find each other using whatever attribute is relevant within your Identity store
+- Federate your Identity server so you can discover others and/or others can discover you
 
-## E-mail
-Given the 3PID `john.doe@example.org`, the following will be performed until a mapping is found:
-- LDAP: lookup the Matrix ID (partial or complete) from a configurable attribute using a dedicated query.
-- DNS: lookup another Identity Server using the domain part of an e-mail and:
-  - Look for a SRV record under `_matrix-identity._tcp.example.org`
-  - Lookup using the base domain name `example.org`
-- Forwarder: Proxy the request to other configurable identity servers.
-
-## Phone number
-Given the phone number `+123456789`, the following lookup logic will be performed:
-- LDAP: lookup the Matrix ID (partial or complete) from a configurable attribute using a dedicated query.
-- Forwarder: Proxy the request to other configurable identity servers.
-
-# Packages
-See [releases]((https://github.com/kamax-io/mxisd/releases)) for native installers of supported systems.  
-If none is available, please use other packages or build from source.
-
-## Debian
-### Download
-See the [releases section](https://github.com/kamax-io/mxisd/releases).
-
-### Configure and run
-After installation:
-1. Copy the sample config file `/etc/mxisd/mxisd-sample.yaml` to `/etc/mxisd/mxisd.yaml`
-2. [Configure](#configuration)
-3. Start the service: `sudo systemctl start mxisd`
-
-### From source
-Requirements:
-- fakeroot
-- dpkg-deb
-
-Run:
-```
-./gradlew buildDeb 
-```
-You will find the debian package in `build/dist`
-
-## Docker
-```
-docker pull kamax/mxisd
-```
-
-For more info, see [the public repository](https://hub.docker.com/r/kamax/mxisd/)
-### From source
-[Build mxisd](#build) then build the docker image:
-```
-./gradlew dockerBuild
-```
-You can run a container of the given image and test it with the following command (adapt volumes host paths):
-```
-docker run -v /data/mxisd/etc:/etc/mxisd -v /data/mxisd/var:/var/mxisd -p 8090:8090 -t kamax/mxisd:latest-dev
-```
-
-# From Source
-## Requirements
-- JDK 1.8
-
-## Build
-```
-git clone https://github.com/kamax-io/mxisd.git
-cd mxisd
-./gradlew build
-```
-then see the [Configuration](#configuration) section.
-
-## Test build
-Start the server in foreground to validate the build:
-```
-java -jar build/libs/mxisd.jar
-```
-
-Ensure the signing key is available:
-```
-$ curl http://localhost:8090/_matrix/identity/api/v1/pubkey/ed25519:0
-{"public_key":"..."}
-```
-
-Test basic recursive lookup (requires Internet connection with access to TCP 443):
-```
-$ curl 'http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=mxisd-lookup-test@kamax.io'
-{"address":"mxisd-lookup-test@kamax.io","medium":"email","mxid":"@mxisd-lookup-test:kamax.io",...}
-```
-
-
-If you enabled LDAP, you can also validate your config with a similar request after replacing the `address` value with something present within your LDAP
-```
-curl "http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=john.doe@example.org"
-```
-
-If you plan on testing the integration with a homeserver, you will need to run an HTTPS reverse proxy in front of it
-as the reference Home Server implementation [synapse](https://github.com/matrix-org/synapse) requires a HTTPS connection
-to an ID server.  
-See the [Integration section](#integration) for more details.
-
-## Install
-After [building](#build) the software, run all the following commands as `root` or using `sudo`
-1. Prepare files and directories:
-```
-# Create a dedicated user
-useradd -r mxisd
-
-# Create bin directory
-mkdir /opt/mxisd
-
-# Create config directory and set ownership
-mkdir /etc/mxisd
-chown mxisd /etc/mxisd
-
-# Create data directory and set ownership
-mkdir /var/opt/mxisd
-chown mxisd /var/opt/mxisd
-
-# Copy <repo root>/build/libs/mxisd.jar to bin directory
-cp ./build/libs/mxisd.jar /opt/mxisd/
-chown mxisd /opt/mxisd/mxisd.jar
-chmod a+x /opt/mxisd/mxisd.jar
-
-# Create symlink for easy exec
-ln -s /opt/mxisd/mxisd.jar /usr/bin/mxisd
-```
-
-2. Copy the config file created earlier `./application.example.yaml` to `/etc/mxisd/mxisd.yaml`
-3. [Configure](#configuration)
-4. Copy `<repo root>/src/systemd/mxisd.service` to `/etc/systemd/system/` and edit if needed
-5. Enable service for auto-startup
-```
-systemctl enable mxisd
-```
-6. Start mxisd
-```
-systemctl start mxisd
-```
-
-# Configuration
-After following the specific instructions to create a config file from the sample:
-1. Set the `matrix.domain` value to the domain value used in your Home Server configuration
-2. Set an absolute location for the signing keys using `key.path`
-3. Configure the E-mail invite sender with items starting in `invite.sender.email`
-
-In case your IS public domain does not match your Matrix domain, see `server.name` and `server.publicUrl` 
-config items.
-
-
-## Backends
-### LDAP (AD, Samba, LDAP)
-If you want to use LDAP backend as an Identity store:
-1. Enable it with `ldap.enabled`
-2. Configure connection options using items starting in `ldap.connection`
-3. You may want to valid default values for `ldap.attribute` items
-
-### SQL (SQLite, PostgreSQL)
-If you want to connect to use a synapse DB (SQLite or PostgreSQL) as Identity store, follow the example config for `sql` config items.
-
-### REST (Webapps/websites integration)
-If you want to use the REST backend as an Identity store:
-1. Enable it with `rest.enabled`
-2. Configure options starting with `rest` and see the dedicated documentation in `docs/backends/rest.md`
-
-# Network Discovery
-To allow other federated Identity Server to reach yours, the same algorithm used for Homeservers takes place:
-1. Check for the appropriate DNS SRV record
-2. If not found, use the base domain
- 
-If your Identity Server public hostname does not match your Matrix domain, configure the following DNS SRV entry 
-and replace `matrix.example.com` by your Identity server public hostname - **Make sure to end with a final dot!**
-```
-_matrix-identity._tcp.example.com. 3600 IN SRV 10 0 443 matrix.example.com.
-``` 
-This would only apply for 3PID that are DNS-based, like e-mails. For anything else, like phone numbers, no federation 
-is currently possible.  
-
-The port must be HTTPS capable. Typically, the port `8090` of mxisd should be behind a reverse proxy which does HTTPS.
-See the [integration section](#integration) for more details.

-# Recurisve lookup config items #
-#################################
-# Configuration items for recursion-type of lookup
 #
-# Lookup access are divided into two types:
-# - Local
-# - Remote
-#
-# This is similar to DNS lookup and recursion and is therefore prone to the same vulnerabilities.
-# By default, only non-public hosts are allowed to perform recursive lookup.
-#
-# This will also prevent very basic endless loops where host A ask host B, which in turn is configured to ask host A,
-# which would then ask host B again, etc.
-
-# Enable recursive lookup globally
-#
-#lookup.recursive.enabled: true
-
-
-# Whitelist of CIDR that will trigger a recursive lookup.
-# The default list includes all private IPv4 address and the IPv6 loopback.
-#
-#lookup.recursive.allowedCidr:
-#  - '127.0.0.0/8'
-#  - '10.0.0.0/8'
-#  - '172.16.0.0/12'
-#  - '192.168.0.0/16'
-#  - '::1/128'
-
-
-# In case no binding is found, query an application server which implements the single lookup end-point
-# to return bridge virtual user that would allow the user to be contacted directly by the said bridge.
-#
-# If a binding is returned, the application server is not expected to sign the message as it is not meant to be
-# reachable from the outside.
-# If a signature is provided, it will be discarded/replaced by this IS implementation (to be implemented).
-#
-# IMPORTANT: This bypass the regular Invite system of the Homeserver. It will be up to the Application Server
-# to handle such invite. Also, if the bridged user were to actually join Matrix later, or if a 3PID binding is found
-# room rights and history would not be transferred, as it would appear as a regular Matrix user to the Homeserver.
-#
-# This configuration is only helpful for Application Services that want to overwrite bridging for 3PID that are
-# handled by the Homeserver. Do not enable unless the Application Server specifically supports it!
-
-# Enable unknown 3PID bridging globally
-#
-#lookup.recursive.bridge.enabled: false
-
-
-# Enable unknown 3PID bridging for hosts that are allowed to perform recursive lookups.
-# Leaving this setting to true is highly recommended in a standard setup, unless this Identity Server
-# is meant to always return a virtual user MXID even for the outside world.
-#
-#lookup.recursive.bridge.recursiveOnly: true
-
-
-# This mechanism can handle the following scenarios:
-#
-# - Single Application Server for all 3PID types: only configure the server value, comment out the rest.
-#
-# - Specific Application Server for some 3PID types, default server for the rest: configure the server value and
-#          each specific 3PID type.
-#
-# - Only specific 3PID types: do not configure the server value or leave it empty/blank, configure each specific
-#          3PID type.
-
-# Default application server to use for all 3PID types. Remove config item or leave empty/blank to disable.
-#
-#lookup.recursive.bridge.server: ''

-#### How to map Matrix attributes with LDAP attributes when performing lookup/auth
-#
-# How should we resolve the Matrix ID in case of a match using the attribute.
-#
-# The following type are supported:
-# - uid : the attribute only contains the UID part of the Matrix ID. e.g. 'john.doe' in @john.doe:example.org
-# - mxid : the attribute contains the full Matrix ID - e.g. '@john.doe:example.org'
-#
-#ldap.attribute.uid.type: 'uid'
-
-
-# The attribute containing the binding itself. This value will be used differently depending on the type.
-#
-# /!\ This should match the synapse LDAP Authenticator 'uid' configuration /!\
-#
-# Typical values:
-# - For type 'uid': 'userPrincipalName' or 'uid' or 'saMAccountName'
-# - For type 'mxid', regardless of the directory type, we recommend using 'pager' as it is a standard attribute and
-#   is typically not used.
-#
-#ldap.attribute.uid.value: 'userPrincipalName'
-
-
-# The display name of the user
-#
-#ldap.attribute.name: 'displayName'

-# During authentication, What to filter potential users by, typically by using a dedicated group.
-# If this value is not set, login check will be performed for all entities within the LDAP

+
+## Binaries
+### Requirements
+- JDK 1.8
+
+### Build
+```bash
+git clone https://github.com/kamax-matrix/mxisd.git
+cd mxisd
+./gradlew build
+```
+
+Create a new configuration file by coping `application.example.yaml` to `application.yaml` and edit to your needs.  
+For advanced configuration, see the [Configure section](configure.md).  
+**NOTE**: `application.yaml` is also called `mxisd.yaml` in some specific installations.
+
+Start the server in foreground to validate the build and configuration:
+```bash
+java -jar build/libs/mxisd.jar
+```
+
+Ensure the signing key is available:
+```bash
+$ curl 'http://localhost:8090/_matrix/identity/api/v1/pubkey/ed25519:0'
+{"public_key":"..."}
+```
+
+Test basic recursive lookup (requires Internet connection with access to TCP 443):
+```bash
+$ curl 'http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=mxisd-federation-test@kamax.io'
+{"address":"mxisd-federation-test@kamax.io","medium":"email","mxid":"@mxisd-lookup-test:kamax.io",...}
+```
+
+If you enabled LDAP, you can also validate your config with a similar request after replacing the `address` value with
+something present within your LDAP
+```bash
+curl 'http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=john.doe@example.org'
+```
+
+If you plan on testing the integration with a homeserver, you will need to run an HTTPS reverse proxy in front of it
+as the reference Home Server implementation [synapse](https://github.com/matrix-org/synapse) requires a HTTPS connection
+to an ID server.  
+
+Next step: [Install your compiled binaries](install/source.md)
+
+## Debian package
+Requirements:
+- fakeroot
+- dpkg-deb
+
+[Build mxisd](#build) then:
+```bash
+./gradlew buildDeb 
+```
+You will find the debian package in `build/dist`.  
+Then follow the instruction in the [Debian package](install/debian.md) document.
+
+## Docker image
+[Build mxisd](#build) then:
+```bash
+./gradlew dockerBuild

+# Concepts
+- [Matrix](#matrix)
+- [mxisd](#mxisd)
+
+## Matrix
+The following concepts are part of the Matrix ecosystem and specification.
+
+### 3PID
+`3PID` stands for Third-Party Identifier.  
+It is also commonly written:
+- `3pid`
+- `tpid`
+
+A 3PID is a globally unique canonical identifier which is made of:
+- Medium, which describes what network it belongs to (Email, Phone, Twitter, Discord, etc.)
+- Address, the actual value people typically use on a daily basis.
+
+mxisd core mission is to map those identifiers to Matrix User IDs.
+
+### Homeserver
+Where a user **account and data** are stored.
+
+### Identity server
+An Identity server:
+- Does lookup of 3PIDs to User Matrix IDs.
+- Does validate 3PIDs ownership, typically by sending a code that the user has to enter in an application/on a website.
+- Does send notifications about room invites where no Matrix User ID could be found for the invitee.
+
+An Identity server:
+- **DOES NOT** store user accounts.
+- **DOES NOT** store user data.
+- **DOES NOT** allow migration of user account and/or data between homeservers. 
+
+### 3PID session
+The fact to validate a 3PID (email, phone number, etc.) via the introduction of a token which was sent to the 3PID address.
+
+## mxisd
+The following concepts are specific to mxisd.
+
+### Identity store
+Where your user accounts and 3PID mappings are stored.
+
+mxisd itself **DOES NOT STORE** user accounts or 3PID mappings.

+- [Identity stores](#identity-stores)

+
+## Concepts
+### Syntax
+The configuration file is [YAML](http://yaml.org/) based, allowing two types of syntax.
+
+Properties-like:
+```yaml
+my.config.item: 'value'
+```
+
+Object-like:
+```yaml
+my:
+  config:
+    item: 'value'
+
+```
+These can also be combined within the same file.  
+Both syntax will be used interchangeably in these documents.
+
+### Variables
+It is possible to copy the value of a configuration item into another using the syntax `${config.key.item}`.  
+Example that will copy the value of `matrix.domain` into `server.name`:
+```yaml
+matrix:
+  domain: 'example.org'
+
+server:
+  name: '${matrix.domain}'
+```
+
+**WARNING:** mxisd might overwrite/adapt some values during launch. Those changes will not be reflected into copied keys.
+
+
+## Matrix
+`matrix.domain`
+Matrix domain name, same as the Homeserver, used to build appropriate Matrix IDs |
+
+---
+
+`matrix.identity.servers`
+Namespace to create arbitrary list of Identity servers, usable in other parts of the configuration |
+
+Example:
+```yaml
+matrix.identity.servers:
+  myOtherServers:
+    - 'https://other1.example.org'
+    - 'https://other2.example.org'
+```
+Create a list under the label `root` containing a single Identity server, `https://matrix.org`
+
+## Server
+- `server.name`: Public hostname of mxisd, if different from the Matrix domain.
+- `server.port`: HTTP port to listen on (unencrypted)
+- `server.publicUrl`: Defaults to `https://${server.name}`
+
+## Storage
+### SQLite
+`storage.provider.sqlite.database`: Absolute location of the SQLite database
+
+## Identity stores
+See the [Identity stores](stores/README.md) for specific configuration
+
+## 3PID Validation sessions
+See the dedicated documents:
+- [Flow](threepids/session/session.md)
+- [Branding](threepids/session/session-views.md)
+
+## Notifications
+- `notification.handler.<3PID medium>`: Handler to use for the given 3PID medium. Repeatable.
+
+Example:
+```yaml
+notification.handler.email: 'sendgrid'
+notification.handler.msisdn: 'raw'
+```
+- Emails notifications would use the `sendgrid` handler, which define its own configuration under `notification.handlers.sendgrid`
+- Phone notification would use the `raw` handler, basic default built-in handler of mxisd
+
+### Handlers
+- `notification.handers.<handler ID>`: Handler-specific configuration for the given handler ID. Repeatable.
+
+Example:
+```yaml
+notification.handlers.raw: ...
+notification.handlers.sendgrid: ...
+```
+
+Built-in:
+- [Raw](threepids/notification/basic-handler.md)

+# Frequently Asked Questions
+### This is all very complicated and I'm getting confused with all the words, concepts and diagrams - Help!
+Matrix is still a very young protocol and there are a whole lot of rough edges.  
+Identity in Matrix is one of the most difficult topic, mainly as it has not received much love in the past years.
+
+We have tried our best to put together documentation that requires almost no knowledge of Matrix inner workings to get a
+first basic setup running which relies on you reading the documentation in the right order:
+- [The Concepts](concepts.md) in few words.
+- [Getting Started](getting-started.md) step-by-step to a minimal working install.
+- [Identity stores](stores/README.md) you wish to fetch data from.
+- [Features](features) you are interested in that will use your Identity store(s) data.
+
+**IMPORTANT**: Be aware that mxisd tries to fit within the current protocol and existing products and basic understanding
+of the Matrix protocol is required for some advanced features.
+
+If all fails, come over to [the project room](https://matrix.to/#/#mxisd:kamax.io) and we'll do our best to get you
+started and answer questions you might have.
+
+### Do I need to use mxisd if I run a Homeserver?
+No, but it is strongly recommended, even if you don't use any Identity store or integration.
+
+In its default configuration, mxisd uses other federated public servers when performing queries.  
+It can also [be configured](features/identity.md#lookups) to use the central matrix.org servers, giving you access to at
+least the same information as if you were not running it.
+
+It will also give your users a choice to make their 3PIDs available publicly, ensuring they are made aware of the
+privacy consequences, which is not the case with the central Matrix.org servers.
+
+So mxisd is like your gatekeeper and guardian angel. It does not change what you already know, just adds some nice
+simple features on top of it.
+
+### I'm not sure I understand what an "Identity server" is supposed to be or do...
+The current Identity service API is more a placeholder, as the Matrix devs did not have time so far to really work on
+what they want to do with that part of the ecosystem. Therefore, "Identity" is currently a misleading word and concept.
+Given the scope of the current Identity Service API, it would be best called "Invitation service".
+
+Because the current scope is so limited and no integration is done with the Homeserver, there was a big lack of features
+for groups/corporations/organisation. This is where mxisd comes in.
+
+mxisd implements the Identity Service API and also a set of features which are expected by regular users, truly living
+up to its "Identity server" name.
+
+### Can I migrate my existing account on another Matrix server with mxisd?
+No.
+
+Accounts cannot currently migrate/move from one server to another.  
+See a [brief explanation document](concepts.md) about Matrix and mxisd concepts and vocabulary.
+
+### I already use the synapse LDAP3 auth provider. Why should I care about mxisd?
+The [synapse LDAP3 auth provider](https://github.com/matrix-org/matrix-synapse-ldap3) is not longer maintained and
+only handles on specific flow: validate credentials at login.
+
+It does not:
+- Auto-provision user profiles
+- Integrate with Identity management
+- Integrate with Directory searches
+
+mxisd is a replacement and enhancement of it, offering coherent results in all areas, which the LDAP3 auth provider
+does not.
+
+### Sydent is the official Identity server implementation of the Matrix team. Why not use that?
+You can, but [sydent](https://github.com/matrix-org/sydent):
+- [should not be used and/or self-hosted](https://github.com/matrix-org/sydent/issues/22)
+- is not meant to be linked to a specific Homeserver / domain
+- cannot handle federation or proxy lookups, effectively isolating your users from the rest of the network
+- forces you to duplicate all your identity data, so people can be found by 3PIDs
+- forces users to enter all their emails and phone numbers manually in their profile
+
+So really, you should go with mxisd.
+
+### Will I loose access to the central Matrix.org/Vector.im Identity data if I use mxisd?
+No.
+
+In its default configuration, mxisd does not talk to the central Identity server matrix.org to avoid leaking your private
+data and those of people you might know.
+
+mxisd [can be configured](features/identity.md#lookups) to talk to the central Identity servers if you wish.
+
+### So mxisd is just a big hack! I don't want to use non-official features!
+mxisd primary concerns are your privacy and to always be compatible with the Matrix ecosystem and the Identity service API.  
+Whenever the API will be updated and/or enhanced, mxisd will follow, remaining 100% compatible with the ecosystem.
+
+### Should I use mxisd if I don't host my own Homeserver?
+No.
+
+It is possible, but it is not supported and the scope of features will be extremely limited.
+Please consider hosting your own Homeserver and using mxisd alongside it.

+## Description
+Authentication is an enhanced feature of mxisd to ensure coherent and centralized identity management.  
+It allows to use Identity stores configured in mxisd to authenticate users on your Homeserver.
+
+Authentication is divided into two parts:
+- [Basic](#basic): authenticate with a regular username.
+- [Advanced](#advanced): same as basic with extra ability to authenticate using a 3PID.
+
+## Basic
+Authentication by username is possible by linking synapse and mxisd together using a specific module for synapse, also
+known as password provider.
+
+### Overview
+An overview of the Basic Authentication process:

+
+### Synapse
+- Install the [password provider](https://github.com/kamax-io/matrix-synapse-rest-auth)
+- Edit your **synapse** configuration:
+  - As described by the auth module documentation
+  - Set `endpoint` to `http://mxisdAddress:8090` - Replace `mxisdAddress` by an IP/host name that provides a direct
+  connection to mxisd.  
+  This **MUST NOT** be a public address, and SHOULD NOT go through a reverse proxy.
+- Restart synapse
+
+### mxisd
+- Configure and enable at least one [Identity store](../stores/README.md)
+- Restart mxisd
+
+### Validate
+Login on the Homeserver using credentials present in one of your Identity stores.
+
+## Next steps
+### Profile auto-fill
+Auto-filling user profile depends on its support by your configured Identity stores.  
+See your Identity store [documentation](../stores/README.md) on how to enable the feature.
+
+
+## Advanced
+The Authentication feature allows users to login to their Homeserver by using their 3PIDs in a configured Identity store.
+
+### Overview
+This is performed by intercepting the Homeserver endpoint `/_matrix/client/r0/login` as depicted below:

+
+```
+
+Steps of user authentication using a 3PID:
+1. The intercepted login request is directly sent to mxisd instead of the Homeserver.
+2. Identity stores are queried for a matching user identity in order to modify the request to use the user name.
+3. The Homeserver, from which the request was intercepted, is queried using the request at previous step.
+   Its address is resolved using the DNS Overwrite feature to reach its internal address on a non-encrypted port.
+4. The response from the Homeserver is sent back to the client, believing it was the HS which directly answered.
+
+### Requirements
+- [Basic Authentication configured and working](#basic)
+- Reverse proxy setup
+- Homeserver
+- Compatible [Identity store](../stores/README.md)
+
+### Configuration
+#### Reverse Proxy
+##### Apache2
+The specific configuration to put under the relevant `VirtualHost`:
+```apache
+ProxyPass /_matrix/client/r0/login http://localhost:8090/_matrix/client/r0/login
+```
+`ProxyPreserveHost` or equivalent **must** be enabled to detect to which Homeserver mxisd should talk to when building results.
+
+Your VirtualHost should now look similar to:
+```apache
+<VirtualHost *:443>
+    ServerName example.org
+    
+    ...
+    
+    ProxyPreserveHost on
+    ProxyPass /_matrix/client/r0/login http://localhost:8090/_matrix/client/r0/login
+    ProxyPass /_matrix/identity http://localhost:8090/_matrix/identity
+    ProxyPass /_matrix http://localhost:8008/_matrix
+</VirtualHost>
+```
+
+#### DNS Overwrite
+Just like you need to configure a reverse proxy to send client requests to mxisd, you also need to configure mxisd with
+the internal IP of the Homeserver so it can talk to it directly to integrate its directory search.
+
+To do so, put the following configuration in your mxisd configuration:
+```yaml
+dns.overwrite.homeserver.client:
+  - name: 'example.org'
+    value: 'http://localhost:8008'
+```
+`name` must be the hostname of the URL that clients use when connecting to the Homeserver.
+You can use `${server.name}` to auto-populate the `value` using the `server.name` configuration option and avoid duplicating it.
+In case the hostname is the same as your Matrix domain and `server.name` is not explicitely set in the config, `server.name` will default to
+`matrix.domain` and will still probably have the correct value.
+
+`value` is the base internal URL of the Homeserver, without any `/_matrix/..` or trailing `/`.

+# Bridge Integration
+To help natural bridge integration into the regular usage of a Matrix client, mxisd provides a way for bridge to reply
+to 3PID queries if no mapping was found, allowing seamless bridging to a network.
+
+This is performed by implementing a specific endpoint on the bridge to map a 3PID lookup to a virtual user.
+
+**NOTE**: This document is incomplete and might be misleading. In doubt, come in our Matrix room.  
+You can also look at our [Email Bridge README](https://github.com/kamax-io/matrix-appservice-email#mxisd) for an example
+of working configuration.
+
+## Configuration
+```yaml
+lookup.recursive.bridge.enabled: <boolean>
+lookup.recursive.bridge.recursiveOnly: <boolean>
+lookup.recursive.bridge.server: <URL to the bridge endpoint for all 3PID medium>
+lookup.recursive.bridge.mappings:
+  <3PID MEDIUM HERE>: <URL to dedicated bridge for that medium>
+
+```
+
+## Integration
+Implement a simplified version of the [Identity service single lookup endpoint](https://kamax.io/matrix/api/identity_service/unstable.html#get-matrix-identity-api-v1-lookup)
+with only the following parameters needed:
+- `address`
+- `medium`
+- `mxid`
+
+Or an empty object if no resolution exists or desired.

+## Description
+This feature allows you to search for existing and/or potential users that are already present in your Identity backend
+or that already share a room with you on the Homeserver.
+
+Without any integration, synapse:
+- Only search within the users **already** known to you or in public rooms
+- Only search on the Display Name and the Matrix ID
+
+By enabling this feature, you can by default:
+- Search on Matrix ID, Display name and 3PIDs (Email, phone numbers) of any users already in your configured backend
+- Search for users which you are not in contact with yet. Super useful for corporations who want to give Matrix access
+internally, so users can just find themselves **prior** to having any common room(s)
+- Add extra attributes of your backend to extend the search
+- Include your homeserver search results to those found by mxisd
+
+By integrating mxisd, you get the default behaviour and a bunch of extras, ensuring your users will always find each other.
+
+## Overview
+This is performed by intercepting the Homeserver endpoint `/_matrix/client/r0/user_directory/search` like so:
+```
+           +----------------------------------------------+
+Client --> | Reverse proxy                                                                         Step 2
+           |                                              Step 1    +-------------------------+

+           |                        /\                              | mxisd - Identity server | -----------> | Backend |
+           |   /_matrix/*            \----------------------------- |                         |  all users   +---------+
+           |        |            Step 4: Send back merged results   +-------------------------+
+           +        |                                                            |
+                    |                                                          Step 3
+                    |                                                            |
+                    |    +------------+                                Search in known users
+                    \--> | Homeserver | <----------------------------------------/
+                         +------------+   /_matrix/client/r0/user_directory/search
+```
+Steps:
+1. The intercepted request is directly sent to mxisd instead of the Homeserver.
+2. Identity stores are queried for any match on the search value sent by the client.
+3. The Homeserver, from which the request was intercepted, is queried using the same request as the client.
+   Its address is resolved using the DNS Overwrite feature to reach its internal address on a non-encrypted port.
+4. Results from Identity stores and the Homeserver are merged together and sent back to the client, believing it was the HS
+which directly answered the request.
+
+## Requirements
+- Reverse proxy setup, which you should already have in place if you use mxisd
+- At least one compatible [Identity store](../stores/README.md) enabled
+  
+## Configuration
+### Reverse Proxy
+#### Apache2
+The specific configuration to put under the relevant `VirtualHost`:
+```apache
+ProxyPass /_matrix/client/r0/user_directory/ http://0.0.0.0:8090/_matrix/client/r0/user_directory/
+```
+`ProxyPreserveHost` or equivalent must be enabled to detect to which Homeserver mxisd should talk to when building
+results.
+
+Your `VirtualHost` should now look like this:
+```apache
+<VirtualHost *:443>
+    ServerName example.org
+    
+    ...
+    
+    ProxyPreserveHost on
+    ProxyPass /_matrix/client/r0/user_directory/ http://localhost:8090/_matrix/client/r0/user_directory/
+    ProxyPass /_matrix/identity http://localhost:8090/_matrix/identity
+    ProxyPass /_matrix http://localhost:8008/_matrix
+</VirtualHost>
+```
+
+#### nginx
+The specific configuration to add under your `server` section is:
+```nginx
+location /_matrix/client/r0/user_directory {
+    proxy_pass http://0.0.0.0:8090/_matrix/client/r0/user_directory;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-For $remote_addr;
+}
+```
+
+Your `server` section should now look like this:
+```nginx
+server {
+    listen 443 ssl;
+    server_name example.org;
+    
+    ...
+    
+    location /_matrix/client/r0/user_directory {
+        proxy_pass http://localhost:8090/_matrix/client/r0/user_directory;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $remote_addr;
+    }
+    
+    location /_matrix/identity {
+        proxy_pass http://localhost:8090/_matrix/identity;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $remote_addr;
+    }
+    
+    location /_matrix {
+        proxy_pass http://localhost:8008/_matrix;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $remote_addr;
+    }
+}
+```
+
+### DNS Overwrite
+Just like you need to configure a reverse proxy to send client requests to mxisd, you also need to configure mxisd with
+the internal IP of the Homeserver so it can talk to it directly to integrate its directory search.
+
+To do so, use the following configuration:
+```yaml
+dns.overwrite.homeserver.client:
+  - name: 'example.org'
+    value: 'http://localhost:8008'
+```
+`name` must be the hostname of the URL that clients use when connecting to the Homeserver.  
+In case the hostname is the same as your Matrix domain, you can use `${matrix.domain}` to auto-populate the value using
+the `matrix.domain` configuration option and avoid duplicating it.
+
+`value` is the base internal URL of the Homeserver, without any `/_matrix/..` or trailing `/`.
+
+## Next steps
+### Homeserver results
+You can configure if the Homeserver should be queried at all when doing a directory search.  
+To disable Homeserver results, set the following in mxisd configuration file:
+```yaml
+directory.exclude.homeserver: true
+```
+
+### 3PID exclusion in search
+You can configure if the 3PID should also be included when doing a directory search.
+By default, a search is performed on the 3PIDs. If you would like to not include them:
+```yaml
+directory.exclude.threepid: true
+```

+# Federation
+Federation is the process by which domain owners can make compatible 3PIDs mapping auto-discoverable by looking for another
+Federated Identity server using the DNS domain part of the 3PID.
+
+Emails are the best candidate for this kind of resolution which are DNS domain based already.  
+On the other hand, Phone numbers cannot be resolved this way.
+
+For 3PIDs which are not compatible with the DNS system, mxisd can be configured to talk to fallback Identity servers like
+the central matrix.org one. See the [Identity feature](identity.md#lookups) for instructions on how to enable it.
+
+Outbound federation is enabled by default while inbound federation is opt-in and require a specific DNS record.

+```
+
+## Inbound
+If you would like to be reachable for lookups over federation, create the following DNS SRV entry and replace
+`matrix.example.com` by your Identity server public hostname:
+```
+_matrix-identity._tcp.example.com. 3600 IN SRV 10 0 443 matrix.example.com.
+``` 
+
+The port must be HTTPS capable which is what you get in a regular setup with a reverse proxy from 443 to TCP 8090 of mxisd.
+
+## Outbound
+If you would like to disable outbound federation and isolate your identity server from the rest of the Matrix network,
+use the following mxisd configuration options:
+```yaml
+lookup.recursive.enabled: false
+invite.resolution.recursive: false
+session.policy.validation.forLocal.toRemote.enabled: false
+session.policy.validation.forRemote.toRemote.enabled: false
+``` 
+
+There is currently no way to selectively disable federation towards specific servers, but this feature is planned.

+# Getting started
+1. [Preparation](#preparation)
+2. [Install](#install)
+3. [Configure](#configure)
+4. [Integrate](#integrate)
+5. [Validate](#validate)
+6. [Next steps](#next-steps)
+
+Following these quick start instructions, you will have a basic setup that can perform recursive/federated lookups and
+talk to the central Matrix.org Identity server.  
+This will be a good ground work for further integration with features and your existing Identity stores.
+
+## Preparation
+You will need:
+- Working Homeserver, ideally with working federation
+- Reverse proxy with regular TLS/SSL certificate (Let's encrypt) for your mxisd domain
+
+As synapse requires an HTTPS connection when talking to an Identity service, **a reverse proxy is required** as mxisd does
+not support HTTPS listener at this time.
+
+For maximum integration, it is best to have your Homeserver and mxisd reachable via the same hostname.
+
+Be aware of a [NAT/Reverse proxy gotcha](https://github.com/kamax-matrix/mxisd/wiki/Gotchas#nating) if you use the same
+hostname.
+
+The following Quick Start guide assumes you will host the Homeserver and mxisd under the same hostname.  
+If you would like a high-level view of the infrastructure and how each feature is integrated, see the
+[dedicated document](architecture.md)
+
+## Install
+Install via:
+- [Debian package](install/debian.md)
+- [ArchLinux](install/archlinux.md)
+- [Docker image](install/docker.md)
+- [Sources](build.md)
+
+See the [Latest release](https://github.com/kamax-matrix/mxisd/releases/latest) for links to each.
+
+## Configure
+**NOTE**: please view the install instruction for your platform, as this step might be optional or already handled for you.
+
+Create/edit a minimal configuration (see installer doc for the location):
+```yaml
+matrix.domain: 'example.org'
+key.path: '/path/to/signing.key.file'
+storage.provider.sqlite.database: '/path/to/mxisd.db'
+```  
+- `matrix.domain` should be set to your Homeserver domain (`server_name` in synapse configuration)
+- `key.path` will store the signing keys, which must be kept safe! If the file does not exist, keys will be generated for you.
+- `storage.provider.sqlite.database` is the location of the SQLite Database file which will hold state (invites, etc.)
+
+If your HS/mxisd hostname is not the same as your Matrix domain, configure `server.name`.  
+Complete configuration guide is available [here](configure.md).
+
+## Integrate
+For an overview of a typical mxisd infrastructure, see the [dedicated document](architecture.md)
+### Reverse proxy
+#### Apache2
+In the `VirtualHost` section handling the domain with SSL, add the following and replace `0.0.0.0` by the internal
+hostname/IP pointing to mxisd.  
+**This line MUST be present before the one for the homeserver!**
+```apache
+ProxyPass /_matrix/identity http://0.0.0.0:8090/_matrix/identity
+```
+
+Typical configuration would look like:
+```apache
+<VirtualHost *:443>
+    ServerName example.org
+    
+    ...
+    
+    ProxyPreserveHost on
+    ProxyPass /_matrix/identity http://localhost:8090/_matrix/identity
+    ProxyPass /_matrix http://localhost:8008/_matrix
+</VirtualHost>
+```
+
+#### nginx
+In the `server` section handling the domain with SSL, add the following and replace `0.0.0.0` with the internal
+hostname/IP pointing to mxisd.
+**This line MUST be present before the one for the homeserver!**
+```nginx
+location /_matrix/identity {
+    proxy_pass http://0.0.0.0:8090/_matrix/identity;
+}
+```
+
+Typical configuration would look like:
+```nginx
+server {
+    listen 443 ssl;
+    server_name example.org;
+    
+    ...
+    
+    location /_matrix/identity {
+        proxy_pass http://localhost:8090/_matrix/identity;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $remote_addr;
+    }
+    
+    location /_matrix {
+        proxy_pass http://localhost:8008/_matrix;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $remote_addr;
+    }
+}
+```
+
+### Synapse
+Add your mxisd domain into the `homeserver.yaml` at `trusted_third_party_id_servers` and restart synapse.  
+In a typical configuration, you would end up with something similar to:
+```yaml
+trusted_third_party_id_servers:
+    - example.org
+```
+It is recommended to remove `matrix.org` and `vector.im` (or any other default entry) from your configuration so only
+your own Identity server is authoritative for your HS.
+
+## Validate
+**NOTE:** In case your homeserver has no working federation, step 5 will not happen. If step 4 took place, consider
+your installation validated.
+
+1. Log in using your Matrix client and set `https://example.org` as your Identity server URL, replacing `example.org` by
+the relevant hostname which you configured in your reverse proxy.
+2. Create a new empty room. All further actions will take place in this room.
+3. Invite `mxisd-federation-test@kamax.io`
+4. The 3PID invite should be turned into a Matrix invite to `@mxisd-lookup-test:kamax.io`.
+5. The invited test user will join the room, send a congratulation message and leave.
+**NOTE:** You might not see a suggestion for the e-mail address, which is normal. Still proceed with the invite.
+  
+If it worked, it means you are up and running and can enjoy mxisd in its basic mode! Congratulations!  
+If it did not work, [get in touch](../README.md#support) and we'll do our best to get you started.
+
+## Next steps
+Once your mxisd server is up and running, there are several ways you can enhance and integrate further with your
+infrastructure:
+
+- [Enable extra features](features/)
+- [Use your own Identity stores](stores/README.md)

+This Identity Store lets you run arbitrary commands to handle the various requests in each support feature.  
+It is the most versatile Identity store of mxisd, allowing you to connect any kind of logic with any executable/script.
+
+## Overview
+Each request can be mapping to a fully customizable command configuration.  
+The various parameters can be provided via any combination of:
+- [Standard Input](https://en.wikipedia.org/wiki/Standard_streams#Standard_input_(stdin))
+- [Command-line arguments](https://en.wikipedia.org/wiki/Command-line_interface#Arguments)
+- [Environment variables](https://en.wikipedia.org/wiki/Environment_variable)
+
+Each of those supports a set of customizable token which will be replaced prior to running the command, allowing to
+provide the input values in any number of ways.
+
+Success and data will be provided via any combination of:
+- [Exit status](https://en.wikipedia.org/wiki/Exit_status)
+- [Standard Output](https://en.wikipedia.org/wiki/Standard_streams#Standard_output_(stdout))
+
+Each of those supports a set of configuration item to decide how to process the value and/or in which format.
+
+All values, inputs and outputs are UTF-8 encoded.
+
+## Configuration
+Each feature comes with a set of possible lookup/action which is mapped to a generic configuration item block.  
+We will use the term `Executable` for each lookup/action and `Processor` for each configuration block.
+
+### Global
+```yaml
+exec.enabled: <boolean>
+```
+Enable/disable the Identity store at a global/default level. Each feature can still be individually enabled/disabled.
+
+#### Tokens
+The following options allow to globally set tokens for value replacement across all features and processors config.  
+Not all features use all tokens, and each feature might also have its own specific tokens. See each feature documentation.
+  
+They can be set within the following scope:
+
+```yaml
+exec.token.<token>: '<value>'
+```
+
+---
+
+The following tokens and default values are available:
+```yaml
+localpart: '{localpart}'
+```
+Localpart of Matrix User IDs
+
+```yaml
+domain: '{domain}'
+```
+Domain of Matrix User IDs
+
+```yaml
+mxid: '{mxid}'
+```
+Full representation of Matrix User IDs
+
+```yaml
+medium: '{medium}'
+```
+Medium of 3PIDs
+
+```yaml
+address: '{address}'
+```
+Address of 3PIDs
+
+```yaml
+type: '{type}'
+```
+Type of query
+
+```yaml
+query: '{query}'
+```
+Query value
+
+### Executable
+*Executable*s have the following options:
+```yaml
+command: '/path/to/executableOrScript'
+
+```
+Set the executable (relative or absolute) path to be executed. If no command is given, the action will return a "neutral"
+result if possible or be skipped altogether.
+
+---
+
+Command line arguments can be given via a list via both YAML formats:
+```yaml
+args:
+ - '-t'
+ - '{token}'
+ - '-v'
+ - 'value'
+```
+or
+```yaml
+args: ['-t', '{token}', '-v', 'value]
+```
+Each argument will be processed for token replacement.
+
+---
+
+Environment variables can be given as key/value pairs:
+```yaml
+env:
+  ENV_VAR_1: 'value'
+  ENV_VAR_2: '{token}'
+``` 
+Each variable value will be processed for token replacement.
+
+#### Input
+Standard input can be configured in the namespaces `input` with:
+- `type`: The format to use
+- `template`: The full or partial template with tokens to be used when generating the input
+
+Not all features and *Executable*s allow for a template to be provided.  
+Templates for listed-based input are not supported at this time.  
+Default templates may be provided per *Executable*.
+
+The following types are available:
+- `json`: Use JSON format, shared with the [REST Identity Store](rest.md)
+- `plain`: Use a custom multi-lines, optionally tab-separated input
+
+#### Output
+Standard output can be configured in the namespaces `output` with:
+- `type`: The format to use
+- `template`: The full or partial template with tokens to be used when processing the output
+
+Not all features and *Executable*s allow for a template to be provided.  
+Templates for listed-based output are not supported at this time.  
+Default templates may be provided per *Executable*.
+
+The following types are available:
+- `json`: Use JSON format, shared with the [REST Identity Store](rest.md)
+- `plain`: Use a custom multi-lines, optionally tab-separated output
+
+### Examples
+#### Basic
+```yaml
+exec.auth.enabled: true
+exec.auth.command: '/opt/mxisd-exec/auth.sh'
+exec.auth.args: ['{localpart}']
+exec.auth.input.type: 'plain'
+exec.auth.input.template: '{password}'
+exec.auth.env:
+  DOMAIN: '{domain}'
+```
+With Authentication enabled, run `/opt/mxisd-exec/auth.sh` when validating credentials, providing:
+- A single command-line argument to provide the `localoart` as username 
+- A plain text string with the password token for standard input, which will be replaced by the password to check
+- A single environment variable `DOMAIN` containing Matrix ID domain, if given
+
+The command will use the default values for:
+- Success exit status of `0`
+- Failure exit status of `1`
+- Any other exit status considered as error
+- The standard output processing as not processed
+
+#### Advanced
+Given the fictional `placeholder` feature:
+```yaml
+exec.enabled: true
+exec.token.mxid: '{matrixId}'
+
+exec.placeholder.token.localpart: '{username}'
+exec.placeholder.command: '/path/to/executable'
+exec.placeholder.args:
+  - '-u'
+  - '{username}'
+exec.placeholder.env:
+  MATRIX_DOMAIN: '{domain}'
+  MATRIX_USER_ID: '{matrixId}'
+  
+exec.placeholder.output.type: 'json'
+exec.placeholder.exit.success: [0, 128]
+exec.placeholder.exit.failure: [1, 129]
+```
+With:
+- The Identity store enabled for all features
+- A global specific token `{matrixId}` for Matrix User IDs, replacing the default `{mxid}`
+
+Running `/path/to/executable` providing:
+- A custom token for localpart, `{username}`, used as a 2nd command-line argument
+- An extracted Matrix User ID `localpart` provided as the second command line argument, the first one being `-u` 
+- A password, the extracted Matrix `domain` and the full User ID as arbitrary environment variables, respectively
+  `PASSWORD`, `MATRIX_DOMAIN` and `MATRIX_USER_ID`
+
+After execution:
+- Process stdout as [JSON](https://en.wikipedia.org/wiki/JSON)
+- Consider exit status `0` and `128` as success and try to process the stdout for data
+- Consider exit status `1` and `129` as failure and try to process the stdout for error code and message
+
+### Per Feature
+See each dedicated [Feature](#features) section.
+
+## Authentication

+# LDAP Identity store
+## Supported products:
+- Samba
+- Active Directory
+- OpenLDAP
+- NetIQ eDirectory
+
+For NetIQ, replace all the `ldap` prefix in the configuration by `netiq`.
+
+## Features
+|      Name      | Supported? |
+|----------------|------------|
+| Authentication | Yes        |
+| Directory      | Yes        |
+| Identity       | Yes        |
+| Profile        | Yes        |
+
+## Getting started
+### Base
+To use your LDAP backend, add the bare minimum configuration in mxisd config file:
+```yaml
+ldap.enabled: true
+ldap.connection.host: 'ldapHostnameOrIp'
+ldap.connection.port: 389
+ldap.connection.bindDn: 'CN=My Mxisd User,OU=Users,DC=example,DC=org'
+ldap.connection.bindPassword: 'TheUserPassword'
+ldap.connection.baseDn: 'OU=Users,DC=example,DC=org'
+```
+These are standard LDAP connection configuration. mxisd will try to connect on port default port 389 without encryption.
+
+### TLS/SSL connection
+If you would like to use a TLS/SSL connection, use the following configuration options (STARTLS not supported):
+```yaml
+ldap.connection.tls: true
+ldap.connection.port: 12345
+```
+
+### Filter results
+You can also set a default global filter on any LDAP queries:
+```yaml
+ldap.filter: '(memberOf=CN=My Matrix Users,OU=Groups,DC=example,DC=org)'
+```
+This example would only return users part of the group called `My Matrix Users`.
+This can be overwritten or append in each specific flow describe below.
+
+For supported syntax, see the [LDAP library documentation](http://directory.apache.org/api/user-guide/2.3-searching.html#filter).
+
+### Attribute mapping
+LDAP features are based on mapping LDAP attributes to Matrix concepts, like a Matrix ID, its localpart, the user display
+name, their email(s) and/or phone number(s).
+     
+Default attributes are well suited for Active Directory/Samba. In case you are using a native LDAP backend, you will
+most certainly configure those mappings.
+
+#### User ID
+`ldap.attribute.uid.type`: How to process the User ID (UID) attribute:
+- `uid` will consider the value as the [Localpart](https://matrix.org/docs/spec/intro.html#user-identifiers)
+- `mxid` will consider the value as a complete [Matrix ID](https://matrix.org/docs/spec/intro.html#user-identifiers)
+
+`ldap.attribute.uid.value`: Attribute to use to set the User ID value.
+
+The following example would set the `sAMAccountName` attribute as a Matrix User ID localpart:
+```yaml
+ldap.attribute.uid.type: 'uid'
+ldap.attribute.uid.value: 'sAMAccountName'
+```
+
+#### Display name
+Use `ldap.attribute.name`.
+
+The following example would set the display name to the value of the `cn` attribute:
+```yaml
+ldap.attribute.name: 'cn'
+```
+
+#### 3PIDs
+You can also change the attribute lists for 3PID, like email or phone numbers.
+
+The following example would overwrite the [default list of attributes](../../src/main/resources/application.yaml#L67)
+for emails and phone number:
+```yaml
+ldap.attribute.threepid.email:
+  - 'mail'
+  - 'otherMailAttribute'
+
+ldap.attribute.threepid.msisdn:
+  - 'phone'
+  - 'otherPhoneAttribute'
+```
+
+## Features
+### Identity
+Identity features (related to 3PID invites or searches) are enabled and configured using default values and no specific
+configuration item is needed to get started.
+
+#### Configuration
+- `ldap.identity.filter`: Specific user filter applied during identity search. Global filter is used if blank/not set.
+- `ldap.identity.medium`: Namespace to overwrite generated queries from the list of attributes for each 3PID medium.
+
+### Authentication
+No further configuration is needed to use the Authentication feature with LDAP once globally enabled and configured.
+
+Profile auto-fill is enabled by default. It will use the `ldap.attribute.name` and `ldap.attribute.threepid` configuration
+options to get a lit of attributes to be used to build the user profile to pass on to synapse during authentication.
+
+#### Configuration
+- `ldap.auth.filter`: Specific user filter applied during identity search. Global filter is used if blank/not set.
+
+### Directory
+No further configuration is needed to use the Directory feature with LDAP once globally enabled and configured.
+
+#### Configuration
+To set a specific filter applied during directory search, use `ldap.directory.filter`
+
+If you would like to use extra attributes in search that are not 3PIDs, like nicknames, group names, employee number:
+```yaml
+ldap.directory.attribute.other:
+  - 'myNicknameAttribute'
+  - 'memberOf'
+  - 'employeeNumberAttribute'

-# REST backend
+# REST Identity store
 The REST backend allows you to query identity data in existing webapps, like:
 - Forums (phpBB, Discourse, etc.)
 - Custom Identity stores (Keycloak, ...)
 - CRMs (Wordpress, ...)
 - self-hosted clouds (Nextcloud, ownCloud, ...)
 
-It supports the following mxisd flows:
-- Identity lookup
-- Authentication
-
 To integrate this backend with your webapp, you will need to implement three specific REST endpoints detailed below.

+# SQL Identity store
+## Supported Databases
+- PostgreSQL
+- MariaDB
+- MySQL
+- SQLite
+
+## Features
+|      Name      | Supported? |
+|----------------|------------|
+| Authentication | No         |
+| Directory      | Yes        |
+| Identity       | Yes        |
+| Profile        | Yes        |
+
+Due to the implementation complexity of supporting arbitrary hashing/encoding mechanisms or auth flow, Authentication
+will be out of scope of SQL Identity stores and should be done via one of the other identity stores, typically
+the [REST Identity store](rest.md).
+
+## Configuration
+### Basic
+```yaml
+sql.enabled: <boolean>
+```
+Enable/disable the identity store
+
+---
+
+```yaml
+sql.type: <string>
+```
+Set the SQL backend to use:
+- `sqlite`
+- `postgresql`
+- `mariadb`
+- `mysql`
+
+### Connection
+#### SQLite
+```yaml
+sql.connection: <string>
+```
+Set the value to the absolute path to the Synapse SQLite DB file.
+Example: `/path/to/sqlite/file.db`
+
+#### Others
+```yaml
+sql.connection: //<HOST[:PORT]/DB?user=USER&password=PASS
+```
+Set the connection info for the database by replacing the following values:
+- `HOST`: Hostname of the SQL server
+- `PORT`: Optional port value, if not default
+- `DB`: Database name
+- `USER`: Username for the connection
+- `PASS`: Password for the connection
+
+This follow the JDBC URI syntax. See [official website](https://docs.oracle.com/javase/tutorial/jdbc/basics/connecting.html#db_connection_url).
+
+### Directory
+```yaml
+sql.directory.enabled: false
+```
+
+
+---
+
+```yaml
+sql.directory.query:
+  name:
+    type: <string>
+    value: <string>
+  threepid:
+    type: <string>
+    value: <string>
+```
+For each query, `type` can be used to tell mxisd how to process the ID column:
+- `localpart` will append the `matrix.domain` to it
+- `mxid` will use the ID as-is. If it is not a valid Matrix ID, the search will fail.
+
+`value` is the SQL query and must return two columns:
+- The first being the User ID
+- The second being its display name
+
+Example:
+```yaml
+sql.directory.query:
+  name:
+    type: 'localpart'
+    value: 'SELECT idColumn, displayNameColumn FROM table WHERE displayNameColumn LIKE ?'
+  threepid:
+    type: 'localpart'
+    value: 'SELECT idColumn, displayNameColumn FROM table WHERE threepidColumn LIKE ?'

+# Wordpress Identity store
+This Identity store allows you to use user accounts registered on your Wordpress setup.  
+Two types of connections are required for full support:
+- [REST API](https://developer.wordpress.org/rest-api/) with JWT authentication
+- Direct SQL access
+
+## Features
+|      Name      | Supported? |
+|----------------|------------|
+| Authentication | Yes        |
+| Directory      | Yes        |
+| Identity       | Yes        |
+| Profile        | No         |
+
+## Requirements
+- [Wordpress](https://wordpress.org/download/) >= 4.4
+- Permalink structure set to `Post Name`
+- [JWT Auth plugin for REST API](https://wordpress.org/plugins/jwt-authentication-for-wp-rest-api/)
+- SQL Credentials to the Wordpress Database
+
+## Configuration
+### Wordpress
+#### JWT Auth
+Set a JWT secret into `wp-config.php` like so:
+```php
+define('JWT_AUTH_SECRET_KEY', 'your-top-secret-key');
+```
+`your-top-secret-key` should be set to a randomly generated value which is kept secret.
+
+#### Rewrite of `index.php`
+Wordpress is normally configured with rewrite of `index.php` so it does not appear in URLs.  
+If this is not the case for your installation, the mxisd URL will need to be appended with `/index.php`
+
+### mxisd
+Enable in the configuration:
+```yaml
+wordpress.enabled: true
+```
+Configure the URL to your Wordpress installation - see above about added `/index.php`:
+```yaml
+wordpress.rest.base: 'http://localhost:8080'
+```
+Configure the SQL connection to your Wordpress database:
+```yaml
+wordpress.sql.connection: '//127.0.0.1/wordpress?user=root&password=example'
+```
+
+---
+
+By default, MySQL database is expected. If you use another database, use:
+```yaml
+wordpress.sql.type: <string>
+```
+With possible values:
+- `mysql`
+- `mariadb`
+- `postgresql`
+- `sqlite`
+
+---
+
+To configure the tables prefix for default queries, in case a custom value was set during Wordpress install:
+```yaml
+wordpress.sql.tablePrefix: <string>
+```
+By default, the value is set to `wp_`.
