hi , i can call the "manuallogin" method of dnn active directory module with its reference from custom module. it is validating AD users and showing loginstatus  as successful, but in request context, userinfo not taking the values of AD user profile??? please help me

Dagreddy, first could you keep your posts to one thread? Asking the same question multiple times in different threads isn't going to get them answered any faster and is only going to cause confusion.

Second, it's difficult to say where/why your calls to the AD provider code aren't working without seeing your code. The provider passes a lot of information around to different procedures so I don't know if you're even calling the correct location. The best I can suggest is trying to step through the provider code to see what information is passed back from the procedures you're trying to call.
