If ancient 2.1.29 is also the version of the OpenLDAP client libs I'd
strongly recommend to upgrade. There have been countless fixes to
libldap and libldap_r (recommended for multi-threaded apps).

You also won't get support for this old OpenLDAP version on the OpenLDAP
mailing lists (except recommendation to upgrade).

Ciao, Michael.
