From 1287c1d115fb7e8f3954bc05ff65007968403a9c Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Sat, 28 Nov 2009 13:27:06 +1100 Subject: s4-drs: cope with bogus empty attributes from w2k8-r2 w2k8-r2 sometimes sends empty attributes with completely bogus attrid values in a DRS replication response.
