Starts a verified auth session for a remote user. Depending on implementation RemoteAuthTicket will be used to verify the identity of RemoteUserId. The intended usage is to start a verified auth session for any client connecting any other client or server. Having a verified auth session handles identity verification in both peer-to-peer and client-server topologies. In peer-to-peer topologies authentication may not occur due to implicit trust established by the peer-to-peer network.
