Trying to implement SSO for MoodleCloud and all of the documentation seems to refer to configuring Apache to serve up the /auth/shibboleth/index.php as a Shibboleth auth type. That isn't really valid for cloud installs as we don't even have access to those types of configuration options from what I can tell.
I've looked at the plug-in code and it's looking for $_SERVER vars that should be provided if Shibboleth has authenticated correctly. It's not even finding the HTTP_SHIB_APPLICATION_ID/Shib-Application-ID variables. I have no access to Shibboleth logs so I have no idea if the authentication is failing. And I'm not sure which Shibboleth variable names I should be mapping to - are they using the default Shibboleth names?
Any guidance from someone who's configured this before would be appreciated.
