r24914: In response to bug #4892 by Matthias Wallnöfer <mwallnoefer@yahoo.de>,
allow the objectclass module to reconstruct the objectclass hierarchy, rather than using templates. The issue being fixed in particular is that 'top' was not being set on containers. This should ensure we do this right for all objects. Andrew Bartlett (This used to be commit d17a0058ba8492b8b3f81b6f10fc34b3e45bb8a6)
