Hello,

Can someone please tell me how to perform authorization using
GenericPrincipal in WS Secure Conversation.. Or any other way of doing
it..

Even if it required to be done for every web method, there is no name
information available in the SecurityContextToken that is
exchanged...so how can I look up the database or Active Directory for
the user..

Also if I do it at the time when the user signs the request for the
token with his username and then retrieve his groups in
CustomUSernameTokenManager, how do I reference it in the Web Methods??

Please reply to my mail and let me know if there is a solution to
it...Please..

Thanks and Regards,
Sumaira
