Trying out the CAS Authentication piece, and connecting back to my ADFS environment.
cas-authorization-endpoint is set to federation.domain.org and my cas-redirect-uri is set to guacamole.domain.org/guacamole. When I navigate to guacamole.domain.org/guacamole it redirects to the following error
This federation.domain.org page can’t be found
No webpage was found for the web address:https://federation.domain.org/federationmetadata/2007-06/federationmetadata.xml%20?service=https%3A%2F%2Fguacamole.domain.org%2Fguacamole
HTTP ERROR 404
Does my ADFS need any other configuration? Or am I missing some setting?
This will almost certainly not work. ADFS does not implement the CAS authentication protocol. CAS is not just a SSO product, it's a protocol, as well, and the guacamole-auth-cas module implements authentication for the CAS protocol. IIRC, ADFS federation uses SAML, and there's currently no publicly-available version of a SAML module for Guacamole, although there are a couple of folks working on modules, I believe.
