Hi All,

Active Directory

WindowsPrincipal wp=new WindowsPrincipal(WindowsIdentity.GetCurrent());
Response.Write(wp.IsInRole("MyDomain\\domain users"));

And iam getting true, for the same, but my problem is i belong to a
group as WebTeam, Iam not able to validate it

If i give this it return false,

Can somebody help me out how do i validate against my Group
