r11095: Implement wb_getuserdomgroups.
Tridge, if you have the time, you might want to look at a problem I'm having with unix domain stream sockets. From a comment in this commit: /* Using composite_trigger_error here causes problems with the client * socket. Linux 2.6.8 gives me a ECONNRESET on the next read after * writing the reply when I don't wait the 100 milliseconds. */ This is in winbind/wb_cmd_userdomgroups.c:93. The problem I have is that I can not *immediately* send an error reply to the client because the next receive fails. Waiting 100 milliseconds helps. It might also be a problem with epoll(), I don't really know. I'd appreciate if you took a brief look at this, maybe I'm doing something wrong. Thanks, Volker (This used to be commit 3e535cce743710a68a4264e4f66e9c0c4d6770c6)
