- <p>Synapse can be configured to use an OpenID Connect Provider (OP) for
- authentication, instead of its own local password database.</p>
- <p>Any OP should work with Synapse, as long as it supports the authorization code
- flow. There are a few options for that:</p>
- <ul>
- <li>
- <p>start a local OP. Synapse has been tested with <a href="https://www.ory.sh/docs/hydra/">Hydra</a> and
- <a href="https://github.com/dexidp/dex">Dex</a>. Note that for an OP to work, it should be served under a
- secure (HTTPS) origin. A certificate signed with a self-signed, locally
- trusted CA should work. In that case, start Synapse with a <code>SSL_CERT_FILE</code>
- environment variable set to the path of the CA.</p>
- </li>
- <li>
- <p>set up a SaaS OP, like <a href="https://developers.google.com/identity/protocols/oauth2/openid-connect">Google</a>, <a href="https://auth0.com/">Auth0</a> or
- <a href="https://www.okta.com/">Okta</a>. Synapse has been tested with Auth0 and Google.</p>
- </li>
- </ul>
- <p>It may also be possible to use other OAuth2 providers which provide the
- <a href="https://tools.ietf.org/html/rfc6749#section-4.1">authorization code grant type</a>,
- such as <a href="https://developer.github.com/apps/building-oauth-apps/authorizing-oauth-apps">Github</a>.</p>
- <h2 id="preparing-synapse"><a class="header" href="#preparing-synapse">Preparing Synapse</a></h2>
- <p>The OpenID integration in Synapse uses the
- <a href="https://pypi.org/project/Authlib/"><code>authlib</code></a> library, which must be installed
- as follows:</p>
- <ul>
- <li>
- <p>The relevant libraries are included in the Docker images and Debian packages
- provided by <code>matrix.org</code> so no further action is needed.</p>
- </li>
- <li>
- <p>If you installed Synapse into a virtualenv, run <code>/path/to/env/bin/pip install matrix-synapse[oidc]</code> to install the necessary dependencies.</p>
- </li>
- <li>
- <p>For other installation mechanisms, see the documentation provided by the
- maintainer.</p>
- </li>
- </ul>
- <p>To enable the OpenID integration, you should then add a section to the <code>oidc_providers</code>
- setting in your configuration file.
- See the <a href="usage/configuration/config_documentation.html#oidc_providers">configuration manual</a> for some sample settings, as well as
- the text below for example configurations for specific providers.</p>
- <h2 id="oidc-back-channel-logout"><a class="header" href="#oidc-back-channel-logout">OIDC Back-Channel Logout</a></h2>
- <p>Synapse supports receiving <a href="https://openid.net/specs/openid-connect-backchannel-1_0.html">OpenID Connect Back-Channel Logout</a> notifications.</p>
- <p>This lets the OpenID Connect Provider notify Synapse when a user logs out, so that Synapse can end that user session.
- This feature can be enabled by setting the <code>backchannel_logout_enabled</code> property to <code>true</code> in the provider configuration, and setting the following URL as destination for Back-Channel Logout notifications in your OpenID Connect Provider: <code>[synapse public baseurl]/_synapse/client/oidc/backchannel_logout</code></p>
- <h2 id="sample-configs"><a class="header" href="#sample-configs">Sample configs</a></h2>
- <p>Here are a few configs for providers that should work with Synapse.</p>
- <h3 id="microsoft-azure-active-directory"><a class="header" href="#microsoft-azure-active-directory">Microsoft Azure Active Directory</a></h3>
- <p>Azure AD can act as an OpenID Connect Provider. Register a new application under
- <em>App registrations</em> in the Azure AD management console. The RedirectURI for your
- application should point to your matrix server:
- <code>[synapse public baseurl]/_synapse/client/oidc/callback</code></p>
- <p>Go to <em>Certificates & secrets</em> and register a new client secret. Make note of your
- Directory (tenant) ID as it will be used in the Azure links.
- Edit your Synapse config file and change the <code>oidc_config</code> section:</p>
- <pre><code class="language-yaml">oidc_providers:
- - idp_id: microsoft
- idp_name: Microsoft

- <p>Keycloak supports OIDC Back-Channel Logout, which sends logout notification to Synapse, so that Synapse users get logged out when they log out from Keycloak.
- This can be optionally enabled by setting <code>backchannel_logout_enabled</code> to <code>true</code> in the Synapse configuration, and by setting the "Backchannel Logout URL" in Keycloak.</p>
