Central Authentication Service (CAS) is a Web Single-Sign-On (WebSSO), developed by JA-SIG as an open source project. CAS enables you to work on different applications to log in only once and to be recognized and authenticated by all applications. Details about CAS can be found here.
The CAS integration consists of two steps:
Installing or configuring the CAS server.
Setting up the portal to use the CAS server.
For more information on CAS configuration, see here.
