From f1b393ce11245fb7bc4488a5377fa516fb4ae17a Mon Sep 17 00:00:00 2001
From: Andrew Bartlett <abartlet@samba.org>
Date: Fri, 14 Jun 2002 04:45:04 +0000
Subject: Some updates from ctrlsoft <jelmer@nl.linux.org> to return failure if
 *any* of the passdb backends fail to load (is this the right way? - I think
 so).

Also, I've added some more comments, cleaned up some style etc.
(This used to be commit c8c490bcb84df43be38bdcb48067fec12331e358)
