Class CasAuthenticationEntryPoint

java.lang.Object
org.springframework.security.cas.web.CasAuthenticationEntryPoint
All Implemented Interfaces:
org.springframework.beans.factory.InitializingBean, AuthenticationEntryPoint
public class CasAuthenticationEntryPoint extends Object implements AuthenticationEntryPoint, org.springframework.beans.factory.InitializingBean
Used by the ExceptionTranslationFilter to commence authentication via the JA-SIG Central Authentication Service (CAS).

The user's browser will be redirected to the JA-SIG CAS enterprise-wide login page. This page is specified by the loginUrl property. Once login is complete, the CAS login page will redirect to the page indicated by the service property. The service is a HTTP URL belonging to the current application. The service URL is monitored by the CasAuthenticationFilter, which will validate the CAS login was successful.
