title: Rancher Keycloak authentication setup
body: <p>I'm trying to setup Rancher to use Keycloak as an authentication provider and following the setups laid out <a href="https://rancher.com/docs/rancher/v2.x/en/admin-settings/authentication/keycloak/" rel="nofollow noreferrer">here</a>. The last step says to export the metadata in the <code>SAML Metadata IDPSSODescriptor</code> format but I only see <code>SAML Metadata SPSSODescriptor</code> as an option. I've tried using that but authentication isn't working - it opens another window with the same Keycloak setup page when clicking the <em>Authenticate with Keycloak</em> button to validate the setup. There are no errors in the Docker logs for either the Rancher or Keycloak containers when running <code>docker logs CONTAINER</code> command.</p>
  
  <p>I'm wondering if I need to do something specific to setup Keycloak as an IDP to get the correct metadata option but I can't find anything in their documentation.</p>
