For users authenticated through client application services, the static Thread.CurrentPrincipal property is set to a ClientRolePrincipal object that enables access to the configured role service. The method resets the CurrentPrincipal property to a WindowsPrincipal object that contains the current WindowsIdentity. After you call this method, you can no longer retrieve roles for the user through the ClientRoleProvider class. To reauthenticate the current user, call the ClientWindowsAuthenticationMembershipProvider.ValidateUser method.
