Hmm, this is a debug message of OpenLDAP's libldap. Never saw this. 
Which version of OpenLDAP is installed there? CentOS is based on Fedora? 
Red Hat / Fedora is far behind with its OpenLDAP version. Any chance for 
a library mix with another libldap? Could you please check which libldap 
is dynamically linked? Use ldd for that.

On my system where OpenLDAP is separately compiled and installed to 
prefix /opt/openldap-2.3:

# ldd /usr/lib/python/site-packages/_ldap.so
         linux-gate.so.1 =>  (0xffffe000)
         libldap_r-2.3.so.0 => /opt/openldap-2.3/lib/libldap_r-2.3.so.0

         liblber-2.3.so.0 => /opt/openldap-2.3/lib/liblber-2.3.so.0

It shouldn't be a problem. It works for me very often. I believe it's an 
issue with your local installation.

Strange.

Ciao, Michael.
