Password auth provider modules
|
|
==============================
|
|
|
|
Password auth providers offer a way for server administrators to integrate
|
|
their Synapse installation with an existing authentication system.
|
|
|
|
A password auth provider is a Python class which is dynamically loaded into
|
|
Synapse, and provides a number of methods by which it can integrate with the
|
|
authentication system.
|
|
|
|
This document serves as a reference for those looking to implement their own
|
|
password auth providers.
|
|
|
|
Required methods
|
|
----------------
|
|
|
|
Password auth provider classes must provide the following methods:
|
|
|
|
*class* ``SomeProvider.parse_config``\(*config*)
|
|
|
|
This method is passed the ``config`` object for this module from the
|
|
homeserver configuration file.
|
|
|
|
It should perform any appropriate sanity checks on the provided
|
|
configuration, and return an object which is then passed into ``__init__``.
|
|
|
|
*class* ``SomeProvider``\(*config*, *account_handler*)
|
|
|
|
The constructor is passed the config object returned by ``parse_config``,
|
|
and a ``synapse.handlers.auth._AccountHandler`` object which allows the
|
|
password provider to check if accounts exist and/or create new ones.
|
|
|
|
``someprovider.check_password``\(*user_id*, *password*)
|
|
|
|
This is the method that actually does the work. It is passed a qualified
|
|
``@localpart:domain`` user id, and the password provided by the user.
|
|
|
|
The method should return a Twisted ``Deferred`` object, which resolves to
|
|
``True`` if authentication is successful, and ``False`` if not.
|
|
|
|
Optional methods
|
|
----------------
|
|
|
|
Password provider classes may optionally provide the following methods.
|
|
|
|
*class* ``SomeProvider.get_db_schema_files()``
|
|
|
|
This method, if implemented, should return an Iterable of ``(name,
|
|
stream)`` pairs of database schema files. Each file is applied in turn at
|
|
initialisation, and a record is then made in the database so that it is
|
|
not re-applied on the next start.
