Rocket.Chat SaaS
Simple SAML php
As a popular open-source IdP, SimpleSAMLphp can be used to provide an authentication endpoint for Rocket.Chat and the build-in SAML support. Assuming that you have a SimpleSAMLphp IdP up and running - QuickStart instructions here, you can find the metadata for the Rocket.Chat SAML Service Provider (SP) here, where 'my-app' is whatever you put in the Custom Provider box in the Rocket.Chat SAML admin page:
https://my-rocketchat-domain.tld/_saml/metadata/my-app
  1. 1.
    Copy the XML on this page
  2. 2.
    Open the metadata converter page in your SimpleSAMLphp admin UI found at: /admin/metadata-converter.php
  3. 3.
    Paste the XML, and submit it
  4. 4.
    Copy the resulting PHP output to the file in your SimpleSAMLphp installation under metadata: /metadata/saml20-sp-remote.php
  5. 5.
    You should now see your SP on the SimpleSAMLphp Federation page, listed as a trusted SAML 2.0 SP at: module.php/core/frontpage_federation.php
