From 9066025a8a4afe1f7f559c455d86fc023792ed17 Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Tue, 29 Sep 1998 20:24:17 +0000
Subject: Got very strict about the differences and uses of uid_t, gid_t and
 vuid. Added sys_getgroups() to get around the int * return problem. Set
 correct datatypes for all uid, gid and vuid variables. Jeremy. (This used to
 be commit e570db46fc3a78e499523fd342e9a34cebb18998)
