I'm not entirely sure how to handle other platforms yet. The complicated part
is passing the user credentials through the socket. I know that some platforms
don't support it (like Solaris, OSX, and OpenBSD), and others do it
differently. I need people to try it on other platforms and possibly port the
The important bits are in src/lib/Libnet/net_server.c (creating the socket),
src/lib/Libifl/pbsD_connect.c (sending ucreds) and src/server/process_request.c
I've added --enable-unixsockets to configure and a test for
'CMSG_SPACE(sizeof(struct ucred))'. The result of that test is the default for
Note that this feature is also a precursor for a future persistent pbs_iff
daemon that will do the same thing for remote connections.
