SQL Identity store

Supported Databases

PostgreSQL
MariaDB
MySQL
SQLite

Features

Name	Supported?
Authentication	No
Directory	Yes
Identity	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.

Configuration

Basic

sql.enabled: <boolean>

Enable/disable the identity store

sql.type: <string>

Set the SQL backend to use:

sqlite
postgresql
mariadb
mysql

Connection

SQLite

sql.connection: <string>

Set the value to the absolute path to the Synapse SQLite DB file. Example: /path/to/sqlite/file.db

Others

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.

Directory

sql.directory.enabled: false

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:

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 ?'

Identity

sql.identity.type: <string>
sql.identity.query: <string>
