We are running the Shibboleth IdP v4.0.1 which supports the CAS v3 protocol.
All University of Maryland College Park (UMDCP) students, faculty, staff, and affiliates. Additionally employees and affiliates of UMES, UMCES, & USMO can authenticate.
For certain sites, former students and/or associates (guests) can authenticate. Please contact IT Service Desk if you desire this functionality.
CAS will return the user's Directory ID. Additional attributes are available upon request.
See the CAS web site (note that we currently support CAS 1/2). In particular, you will want to check out the clients which have already been implemented in a variety of environments/languages.
Here is a little presentation on how a CAS authentication works.
See the CAS Protocol specification for details on the parameters.
All users of CAS are strongly encouraged to subscribe to the UMDIRECTORY listserv list by sending a message to listserv@listserv.umd.edu with a body of Subscribe UMDIRECTORY.
For additional questions and or assistance please contact the administrators at shibboleth@umd.edu.
