commit c9efd454c5ffe0126bb21fdaadd421d71c38e2f7
Author: Volker Lendecke <vl at samba.org>
Date:   Thu Mar 12 17:23:17 2009 +0100

    Fix bug 6157
    
    This patch picks the alphabetically smallest one of the multi-value attribute
    "uid". This fixes a regression against 3.0 and also becomes deterministic.
