Using Samba's ldbsearch as a LDAP client, I am unable to reproduce the
issue, so there may be something more to this than meets the eye.

Can you get me a wireshark trace of this failing with Citrix, plus if
you can reproduce the failure with Apache DS or another tool, one of it
failing and another of it working, it might give me what I need to chase
this down.
