org.acegisecurity.adapters.cas
Class CasPasswordHandlerProxy  

java.lang.Object
  org.acegisecurity.adapters.cas.CasPasswordHandlerProxy

---

public class CasPasswordHandlerProxy

extends java.lang.Object

Enables CAS to use the Acegi Security System for authentication.

This class works along with CasPasswordHandler to enable users to easily migrate from stand-alone Acegi Security System deployments to enterprise-wide CAS deployments.

It should be noted that the Acegi Security System will operate as a CAS client irrespective of the PasswordHandler used on the CAS server. In other words, this class need not be used on the CAS server if not desired. It exists solely for the convenience of users wishing have CAS delegate to an Acegi Security System-based AuthenticationManager.

This class works requires a properly configured CasPasswordHandler. On the first authentication request, the class will use Spring's WebApplicationContextUtils.getWebApplicationContext(ServletContext sc)>WebApplicationContextUtils.getWebApplicationContext(ServletContext sc) 55 method to obtain an ApplicationContext instance, inside which must be a configured CasPasswordHandler instance. The CasPasswordHandlerProxy will then delegate authentication requests to that instance.

To configure CAS to use this class, edit CAS' web.xml and define the edu.yale.its.tp.cas.authHandler context parameter with the value org.acegisecurity.adapters.cas.CasPasswordHandlerProxy.
