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

See CVS:

Revision 1.22

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.
