|
||
|
|
<p>The <a href="https://github.com/jbittel/django-mama-cas">django-mama-cas</a> project is an
|
||
|
|
easy to run CAS implementation built on top of Django.</p>
|
||
|
|
<h2 id="prerequisites"><a class="header" href="#prerequisites">Prerequisites</a></h2>
|
||
|
|
<ol>
|
||
|
|
<li>Create a new virtualenv: <code>python3 -m venv <your virtualenv></code></li>
|
||
|
|
<li>Activate your virtualenv: <code>source /path/to/your/virtualenv/bin/activate</code></li>
|
||
|
|
<li>Install Django and django-mama-cas:
|
||
|
|
<pre><code>python -m pip install "django<3" "django-mama-cas==2.4.0"
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>Create a Django project in the current directory:
|
||
|
|
<pre><code>django-admin startproject cas_test .
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>Follow the <a href="https://django-mama-cas.readthedocs.io/en/latest/installation.html#configuring">install directions</a> for django-mama-cas</li>
|
||
|
|
<li>Setup the SQLite database: <code>python manage.py migrate</code></li>
|
||
|
|
<li>Create a user:
|
||
|
|
<pre><code>python manage.py createsuperuser
|
||
|
|
</code></pre>
|
||
|
|
<ol>
|
||
|
|
<li>Use whatever you want as the username and password.</li>
|
||
|
|
<li>Leave the other fields blank.</li>
|
||
|
|
</ol>
|
||
|
|
</li>
|
||
|
|
<li>Use the built-in Django test server to serve the CAS endpoints on port 8000:
|
||
|
|
<pre><code>python manage.py runserver
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
<p>You should now have a Django project configured to serve CAS authentication with
|
||
|
|
a single user created.</p>
|
||
|
|
<h2 id="configure-synapse-and-element-to-use-cas"><a class="header" href="#configure-synapse-and-element-to-use-cas">Configure Synapse (and Element) to use CAS</a></h2>
|
||
|
|
<ol>
|
||
|
|
<li>Modify your <code>homeserver.yaml</code> to enable CAS and point it to your locally
|
||
|
|
running Django test server:
|
||
|
|
<pre><code class="language-yaml">cas_config:
|

server_url: "http://localhost:8000"

|

|
|
#displayname_attribute: name
|
||
|
|
#required_attributes:
|

|
|
# name: value
|
||
|
|
</code></pre>
|
||
|
|
</li>
|
||
|
|
<li>Restart Synapse.</li>
|
||
|
|
</ol>
|
||
|
|
<p>Note that the above configuration assumes the homeserver is running on port 8081
|
||
|
|
and that the CAS server is on port 8000, both on localhost.</p>
|
||
|
|
<h2 id="testing-the-configuration"><a class="header" href="#testing-the-configuration">Testing the configuration</a></h2>
|
||
|
|
<p>Then in Element:</p>
|
||
|
|
<ol>
|
||
|
|
<li>Visit the login page with a Element pointing at your homeserver.</li>
|
||
|
|
<li>Click the Single Sign-On button.</li>
|
||
|
|
<li>Login using the credentials created with <code>createsuperuser</code>.</li>
|
||
|
|
<li>You should be logged in.</li>
|

</ol>
|

<p>If you want to repeat this process you'll need to manually logout first:</p>
