Thank you for your answer.
I chose another way this morning, because I need the NetMeeting compat.
I'll take the newer OpenLDAP 2.1.x release which has a back-perl module, which 
uses an embedded perl interpreter inside the slapd process; and I'll change 
the code to put all requests against a MySQL database. I examined the perl 
script in the NDK, and the problems don't araise because of the regex one 
might think, the problem is the back-translation to the real ldap server.
I think this will give me much more reliable performance.
Anyway, I'm looking forward to the next release.

Cheers,
Stefan
