## 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.
@@ -11,24 +23,34 @@ With mxisd integration, you can:
- 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)
- Use any attribute of your backend to extend the search!
- Include your homeserver search results to those found by mxisd (default behaviour, no configuration required)
By integrating mxisd, you get the default behaviour with all the 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 +-------------------------+
Client --> | Reverse proxy Step 2
| Step 1 +-------------------------+
| /_matrix/client/r0/user_directory/search ----------> | | Search in +---------+
| /\ | 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. Enabled backends are queried for any math 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 backends 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

## Configuration
### Reverse proxy
### Reverse Proxy
Apache2 configuration to put under the relevant virtual domain:
```
ProxyPreserveHost on
ProxyPass /_matrix/identity/ http://mxisdInternalIpAddress:8090/_matrix/identity/
ProxyPass /_matrix/client/r0/user_directory/ http://mxisdInternalIpAddress:8090/_matrix/client/r0/user_directory/
ProxyPass /_matrix/ http://HomeserverInternalIpAddress:8008/_matrix/
```
`ProxyPreserveHost` or equivalent must be enabled to detect to which Homeserver mxisd should talk to when building
results.
### Backend
### 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:
```
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 intenral URL of the Homeserver, without any `/_matrix/..` or trailing `/`.
### Backends

Configuration structure has been altered so queries are automatically built from a global or specific filter and a list
of attributes. To ensure Directory feature works, here how the LDAP configuration should look like:
