I got some more information this morning. First, BSD/OS doesn't like to
have the credentials record attached to the message. I was getting
"Invalid argument" when I did that. It just wants the packet. Second,
BSD/OS has a LOCAL_CREDS call to pass the credentials. I am working on
another patch but will get back to this shortly.
"To get credentials sent (once on a stream socket, every time on
a datagram socket) you just want to do a setsockopt() to set
the LOCAL_CREDS option:
int on = 1;
error = setsockopt(s, 0, LOCAL_CREDS, &on, sizeof on);
