Folks, Even though clients joined to domain can get sid by using "net getdomainsid", I can't get it from the domain server. I don't know if it's related, but the smbd log on server is full of those messages: [2009/05/28 08:37:25, 0] lib/util_sock.c:get_peer_addr(1224) getpeername failed. Error was Socket is not connected [2009/05/28 08:37:26, 0] smbd/server.c:open_sockets_smbd(531) open_sockets_smbd: accept: Software caused connection abort Thanks in advance!
