I am developing an application using Struts and Tiles in WSAD 5 . I have also created some Roles and mapped them to groups defined in LDAP . For accessing the protected resource, I am employing the Form based Login (thru j_security_check ). Problem is this once the User gets logged in, the method "IsUserInRole" returns the correct value but when a Post is done to any Action, the same method starts returning "false" for the logged in User. Do I need to set up some extra configuration or ???. Any comments will be highly appreciated.
