  137. <p>https://fujifish.github.io/samling/samling.html (https://github.com/fujifish/samling) is a great resource for being able to tinker with the
  138. SAML options within Synapse without needing to deploy and configure a complicated software stack.</p>
  139. <p>To make Synapse (and therefore Element) use it:</p>
  140. <ol>
  141. <li>Use the samling.html URL above or deploy your own and visit the IdP Metadata tab.</li>
  142. <li>Copy the XML to your clipboard.</li>
  143. <li>On your Synapse server, create a new file <code>samling.xml</code> next to your <code>homeserver.yaml</code> with
  144. the XML from step 2 as the contents.</li>
  145. <li>Edit your <code>homeserver.yaml</code> to include:
  146. <pre><code class="language-yaml">saml2_config:
  147. sp_config:
  148. allow_unknown_attributes: true # Works around a bug with AVA Hashes: https://github.com/IdentityPython/pysaml2/issues/388
  149. metadata:
  150. local: [&quot;samling.xml&quot;]
  151. </code></pre>
  152. </li>
  153. <li>Ensure that your <code>homeserver.yaml</code> has a setting for <code>public_baseurl</code>:
  154. <pre><code class="language-yaml">public_baseurl: http://localhost:8080/
  155. </code></pre>
  156. </li>
  157. <li>Run <code>apt-get install xmlsec1</code> and <code>pip install --upgrade --force 'pysaml2&gt;=4.5.0'</code> to ensure
  158. the dependencies are installed and ready to go.</li>
  159. <li>Restart Synapse.</li>
  160. </ol>
  161. <p>Then in Element:</p>
  162. <ol>
  163. <li>Visit the login page and point Element towards your homeserver using the <code>public_baseurl</code> above.</li>
  164. <li>Click the Single Sign-On button.</li>
  165. <li>On the samling page, enter a Name Identifier and add a SAML Attribute for <code>uid=your_localpart</code>.
  166. The response must also be signed.</li>
  167. <li>Click &quot;Next&quot;.</li>
  168. <li>Click &quot;Post Response&quot; (change nothing).</li>
  169. <li>You should be logged in.</li>
  170. </ol>
  171. <p>If you try and repeat this process, you may be automatically logged in using the information you
  172. gave previously. To fix this, open your developer console (<code>F12</code> or <code>Ctrl+Shift+I</code>) while on the
  173. samling page and clear the site data. In Chrome, this will be a button on the Application tab.</p>
