I don't see how steved's changes will fix this problem. If the client has a mapping, it will (MUST) send the mapped uid/gid and the server still has to make sense of that. Ditto if the server has a mapping, and the client does not. steved's patches only help if neither the client nor the server can map the uid/gids to a name@domain format.
