I tried to build python-ldap against libldap_r from OpenLDAP's=20
REL_ENG_2 branch by simply modifying setup.cfg:

libs =3D ldap_r lber sasl

The build went fine. ldd shows output like expected:

$ ldd build/lib.linux-i686-2.2/_ldap.so
         libldap_r.so.2 =3D> /usr/lib/libldap_r.so.2 (0x4001f000)
         liblber.so.2 =3D> /usr/lib/liblber.so.2 (0x4004b000)
         libsasl.so.7 =3D> /usr/lib/libsasl.so.7 (0x40055000)
[..]

But import does not work.

$ python -c "import ldap"
Traceback (most recent call last):
   File "<string>", line 1, in ?
   File "/usr/lib/python2.2/site-packages/ldap/__init__.py", line=20
5, in ?
     from _ldap import *
ImportError: /usr/lib/python2.2/site-packages/_ldap.so: undefined=20
symbol: ldap_first_reference

Anyone willing to dig into this?

Ciao, Michael.
