Make sure that we respect the difference between both versions in
our LDAP module and do not pass serverctrls and clientctrls when
they are not supported. NotImplementedException is raised when the
options are used with this version.

This may be overkill, but would it be better to use introspection to
determine if the arguments are supported?
import ldap
import inspect
signature = inspect.getargspec(ldap.ldapobject.LDAPObject.rename_s)
if 'serverctrls' in signature.args:
_EXTENDED_RENAME_S = True
else:
_EXTENDED_RENAME_S = False

Yes, I believe that would be overkill. If the module exports its
version, why not use it.
The reason is in RHEL patches are often backported w/o the version being
affected so merely checking versions may not be sufficient.
A simpler solution would be that our wrapper would just not use the
extra arguments at all. We're technically wrapping the old version (or
better) of python-ldap, so I don't see why it would hurt.
It would also have the advantage that we couldn't use the extra
arguments in our code, as opposed to getting errors when someone happens
to try with the old version.
Yes, this would work in this rename case.

Ok, I took this path with my patch too. Tested with Fedora 17 + RHEL-6.

There's a typo: "NOTICE: python-ldap of version 2.3.10 and lower does not
support serverctrls and clientctrls *fir* rename_s operation".

You have more keen eyes that I do :-) Fixed patch attached.
Martin
ACK, pushed to master and ipa-3-0
