From 684aa5adef7c8f61e626983ef2a79156fcb14f3d Mon Sep 17 00:00:00 2001
From: Tim Potter <tpot@samba.org>
Date: Tue, 2 May 2006 05:14:00 +0000
Subject: r15389: Add some better torture tests for LdbMessage.

Fix up behaviour of Ldb.__setitem__() function.  It should overwrite the
element data.

Add wrapper for ldb_msg_sanity_check().
(This used to be commit d67e055f86a62d0e61fd20d75b252a6211618f7b)
