Yes, right, but I would say whatever the third party LDAP server does
wrong, it should not result in a wrong behaviour on the client side
(i.e. in the OpenLDAP library).

This would be great.
As I said in the report, our actual problem are the CLOSE-WAITs which
are created by the OpenLDAP library while talking to the Microsoft
Active Directory server. The number of CLOSE_WAITs are steadily
increasing until no more sockets are available and then all connections
fail of course. I know that you need to be able to reproduce the problem
to be able to fix it, so I tried to reproduce the problem with the test
tools. That was the reason I used the test tools provided with the
OpenLDAP library, because I can not send our application.
Can I do anything to help in this case, maybe provide network
traces or such?
