Downloading and Installing a CAS Client

Numerous client implementations for CAS have been developed. Developers and deployers should download client code from the CAS Clients Overview section of the CAS project support website.

Two important things to keep in mind while setting up your application for CAS:

  1. The current CAS Protocol is the 3.0 version. This is distinct from the CAS Server implementation version (currently at 4.x) which implements the CAS 1.0, 2.0, and 3.0 protocols.
  2. The recommended CAS protocol is version 2.0 or greater, with 3.0 preferred where supported for the greatest feature set.
