Performance of OpenLDAP 1.2.x is not too well. There were some messages
explaining why it occurs and there is no fix for 1.2.x available. The
problem is that threading of OpenLDAP 1.2 does not work with Linux.

This shouldn't be a problem with 2.0 but migrating from 1.2 to 2.0 may
bring it's own set of problems. (Note: I say MAY and not WILL.)

I suggest you see if you can give 2.0 a try as well.
