Hi Howard,
Thanks for responding. I was working on the problem for quite awhile, but finally concluded that there wasn't a way to retrieve the information I needed through CAS. Had to ask and make sure!
The reason for going with CAS is the single sign-on authentication. My school is part of a larger district and we are in the process of moving to a single sign-on authentication so both school and district resources are accessible in the same session. Moodle is part of that process too, so need to be able to get CAS working.
From what I understand, I can use CAS for authentication and the LDAP for user data mapping. This is what I will go with. Hopefully that process will go smoothly. If not, you will see me here again!
Phil
