All University of Maryland College Park (UMCP) 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. Contact the IT Service Desk if you desire this functionality.

What are the URLs for the UM CAS server?

Login https://shib.idm.umd.edu/shibboleth-idp/profile/cas/login
Logout https://shib.idm.umd.edu/shibboleth-idp/profile/cas/logout
Service Validate https://shib.idm.umd.edu/shibboleth-idp/profile/cas/serviceValidate

See the CAS Protocol specification for details on the parameters.

NOTE:
In the v3 specification, CAS lists the serviceValidate for v3 as '/p3/serviceValidate'. In our deployment the same functionality is configured in the '/serviceValidate' 
URL above, and the '/p3/serviceValidate URL is not available.
