Class Servlet3AuthenticationFilter

java.lang.Object
  org.jasig.cas.client.util.AbstractConfigurationFilter
      org.jasig.cas.client.util.AbstractCasFilter
          org.jasig.cas.client.jaas.Servlet3AuthenticationFilter

All Implemented Interfaces:

javax.servlet.Filter

public final class Servlet3AuthenticationFilter
extends AbstractCasFilter

Servlet filter performs a programmatic JAAS login using the Servlet 3.0 HttpServletRequest#login() facility. This component should be compatible with any servlet container that supports the Servlet 3.0/JEE6 specification.

The filter executes when it receives a CAS ticket and expects the CasLoginModule JAAS module to perform the CAS ticket validation in order to produce an AssertionPrincipal from which the CAS assertion is obtained and inserted into the session to enable SSO.

If a service init-param is specified for this filter, it supersedes the service defined for the CasLoginModule.
