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