From d16fe72585445e7fd3724a7413ca7e03ee633fc9 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Tue, 19 Oct 2010 11:20:14 +1100 Subject: s4-ldb: cope with NULL oid in controls the ldap server will mark a control with a NULL oid in order to remove it. This prevents a O(n^2) cost in control handling.
