The ASU User module provides ASU customizations on the users.
The elastic query for the user can be set in this form: /admin/config/people/asu_user
We have a private function (was copied from asu_userpicker module) _asu_user_get_elastic_profile_record() that returns the the record of the asurite user given the asurite_id.
If a user with the 'Employee' affiliate logs in with CAS SSO, it will get the employee role in drupal.
