From 536d585c4cfb9d34965c26bdb6b6880ef4f6a4f8 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Thu, 13 Mar 2008 14:11:06 +1100 Subject: Don't search the whole tree for the domains's sid This change removes a dependency on objectclass=domainDNS, and avoids a subtree search when we really know exactly where this record is.
