Subject: r8734: fixed the wins server for the new ldb DN restrictions.

This gets it working, but I'm rather worried about the speed. We used
to get more than 5000 ops/sec, but now we are down to around 15
ops/sec. I suspect a bug in ldb.
(This used to be commit 83727bf72c970effdc5995e2f6e7816a57887b5c)
