Class LoginCheckFilter

java.lang.Object
  extended by edu.internet2.middleware.grouper.ui.LoginCheckFilter
All Implemented Interfaces:
Filter

public class LoginCheckFilter
extends Object
implements Filter

Protects access to resources not listed in the init parameter 'ignore'. Checks if HttpServletRequest.getRemoteUser() has been set, and ensures that a Grouper session is initialised for the user, and that the HttpSession is setup appropriately.

LoginCheckFilter can work with any authentication scheme which causes the getRemoteUser() method to return an appropriate value. This includes other Filters which precede the LoginCheckFilter. The contributed Yale CAS authentication solution uses this approach

If you use Tomcat's default authentication, or some other implementation of HTTP Basic Authentication, then logging out will not work properly
