Interesting. Looks like name->uid translation works, but uid->name don't.
Maybe (for some unknown reason) the reverse NIS map is not there.
Let's debug it:

1. First at the NIS level -- The 'passwd' map is a shortcut to
   the 'passwd.byname' map, let's test the 'passwd.byuid' map:
   * Enumerate:
		ypcat passwd.byuid
   * Match:
		ypmatch 500 passwd.byuid

2. If 1. is OK, test at the NSS level:
		getent passwd 500

Both of these work?

If it's there and you can see it, it's REAL
If it's there and you can't see it, it's TRANSPARENT
If it's not there and you can see it, it's VIRTUAL
If it's not there and you can't see it, it's GONE!
