Yes, OpenLDAP-2.0.11 and especially recent changes in python-ldap CVS
repository require a new version of patches. I've attached them.
The patches don't change the behaviour of python-ldap when compiled
against OpenLDAPv1, but create an alternative code when used with
OpenLDAPv2. Here are the differences between python-ldap compiled
against OpenLDAPv1 and v2 using the patches (seen from the point of view
of a programmer using python-ldap):

   * new constants added for v2 (see constants.c.patch);
   * new errors/exceptions added for v2 (see errors.c.patch);
   * a set of LDAP session attributes changed:
        o only in v1: lberoptions (rw), refhoplimit (rw), options (rw),
          valid (ro);
        o only in v2: version (rw), referrals (rw), restart (rw);
        o in both versions: deref (rw), timelimit (rw), sizelimit (rw),
          errno (ro), error (ro), matched (ro).
   * new type of data added to the Python dictionary returned as a
     result of ldap_result:
     Dictionary keys are DNs, values are entry objects. If the key is
     empty, the value is the list of referrals (URL text strings).

I haven't touched set_rebind_proc in python-ldap yet, because that would
change its API. At the moment you'll get a compile time warning and
possible crash if you use rebind_proc with python-ldap + OpenLDAPv2. It
is impossible to use the v1 set_rebind_proc syntax in v2. It is
theoretically possible to use the OpenLDAPv2 syntax of the function with
the OpenLDAPv1 library, using an internal conversion function. It would
require some programming and (needs your approval) a change to the
python-ldap API. Suggestions?

Regards,
    Konstantin.
