I think it is fixed since release 2.3.7. You should encourage the Debian
maintainer to provide an updated package.

See CVS:

http://python-ldap.cvs.sourceforge.net/viewvc/python-ldap/python-ldap/Modules/functions.c?r1=1.21&r2=1.22

Revision 1.22
Tue Apr 7 16:45:57 2009 UTC (11 months ago) by stroeder
Branch: MAIN
CVS Tags: PYLDAP_REL_2_3_7

Fixed functions.c not to raise ldap.ENCODING_ERROR in function l_ldap_str2dn()
on 64-bit systems (see SF#2725356)

Ciao, Michael.
