When you configure your application to use the ClientWindowsAuthenticationMembershipProvider class, the static Membership::ValidateUser method will use this method for its implementation. The ClientWindowsAuthenticationMembershipProvider::ValidateUser method automatically authenticates the current user and sets the static Thread::CurrentPrincipal property to a ClientRolePrincipal object that contains the current WindowsIdentity. If a ClientRoleProvider is configured for your application, you can use the ClientRolePrincipal object to retrieve user role information from the roles service.
