More info: A tech from my hosting company is telling me this documentation is out of date and the code no longer has the gsaml authentication plugin or the user sync block... this seems odd considering that you are using the gsaml just fine.
Rob, it is impressive that you were able to upgrade your own Moodle with Google Apps integration in a day while our hosting company who specializes in Moodle and is a Moodle Partner can't get ours working in 6 days... and they still seem lost.
My hands are tied at the moment. I would love to attempt to fix it myself, but our host no longer lets their clients have full access. We are not even allowed to upload a plugin. It is one of the frustrating things with going with a Google Partner.
