This page documents how to write a CAS3 AuthenticationHandler. If you already have a CAS2 PasswordHandler or TrustHandler, you can just use it in CAS3 without writing any new code and there is documentation intended specifically for explaining how to convert a CAS2 PasswordHandler to the CAS3 APIs. This page is intended to document CAS3 AuthenticationHandler implementation outside the context of CAS2.

Before we discuss actual APIs and code, it may be helpful to review the concepts of CAS authentication.
The Core Interface
The core interface to implement for your authentication-handling plugin is AuthenticationHandler.
