OpenLDAP 1.x -lldap is not threadaware nor threadsafe.  You need
to provide synchronization necessary to serialize -lldap calls.

Do I need to add a define (POSIX_THREADS seems to be defined in portable.h) somewhere ? Or add flag or define while compiling the openldap sources, or my own sources  ?
Only the servers are threaded... -lldap isn't.

We are developing a threaded version of the library -lldap_r.  It
will use necessary threading functions directly.  Those interested
in contributing to this development are encourged to raise appropriate
discussions on our -develop mailing list.  (I hope to post a
proposed design there shortly).
