commit aa57fd8224a09f26a0f6127024fe739b84eadf49
Author: Nadezhda Ivanova <nivanova at samba.org>
Date:   Tue Sep 21 09:10:54 2010 -0700

    s4-ldap: Fixed a problem with NC's having a parentGUID attribute
    
    NC's other than default NC had a parentGUID, due to an incorrect check of whether
    the object has a parent. Fixed by checking object's instanceType instead.
