From 37569f60f3af50cce034e00e0dc5af026427dbd5 Mon Sep 17 00:00:00 2001
From: Volker Lendecke <vlendec@samba.org>
Date: Sun, 3 Jun 2007 06:54:51 +0000
Subject: r23313: Janitor for tridge:

we need to use tdb_wrap_open in both these backends to allow for
multiple opens.  This is done for notify.tdb. Otherwise we die when a
2nd share with notify is setup
(This used to be commit 40dcccfcf91737ba658fd9e733a431001649d255)
