We are on Guacamole 1.5.4 at the moment, and we have a mandate to implement MFA. We have been working with our IT department and using a test Guacamole server for the configuration testing. We were initially trying OpenID but we kept getting an invalid response_type value. So they suggested SAML, which we implemented and proved that we could log in. However, we do get an error from Guacamole because the MFA doesn't seem to know how to return the response back to our Guacamole server.
So, my question is: how to I implement or configure the Callback URL on our Guacamole server so the response that comes back can be retrieved? Thanks, Harry
