Hmm I saw some postings on using libldap_r with other software 
packages. They used libldap_r *and* libldap for linking.

I tried this in setup.cfg:

libs = ldap_r ldap lber sasl

It seems to work and ldd shows this:

$ ldd /usr/lib/python2.2/site-packages/_ldap.so
         libldap_r.so.2 => /usr/local/openldap2/lib/libldap_r.so.2 
(0x4001f000)
         libldap.so.2 => /usr/local/openldap2/lib/libldap.so.2 
(0x40052000)
         liblber.so.2 => /usr/local/openldap2/lib/liblber.so.2 
(0x40082000)
         libsasl.so.7 => /usr/lib/libsasl.so.7 (0x4008e000)

Can anyone confirm that it's supposed to work that way using both 
libldap_r and libldap for linking? How can I be sure that the 
reentrant version of a ldaplib function is used? (Again revealing 
my lack of C compiling knowledge...)

Ciao, Michael.
