At IU, what is CAS?
CAS currently supports several IU web applications, including One.IU, Duo authentication, TimeKeeping, PeopleSoft, HRMS (payroll), and the employee Paid Time Off (PTO) system. In the future, other IU systems will use CAS as well.
You will be automatically redirected to the CAS login screen when you access one of the supported systems, unless you have already authenticated to CAS during your session. You can also reach the CAS login screen directly at:
CAS currently supports three types of authentication: Active Directory, Duo, and Guest. CAS clients can be deployed on a combination of platforms including Windows, Linux, and both Apache and IIS. CAS supports a variety of tools and languages including Java, Active Server Pages, and Perl.
While CAS authentication will only return a username, you can use that username to query ADS and retrieve more information. See At IU, how can I query ADS using LDAP?
