[Setup] LDAP installation error

[rscrane]

I am trying to enable LDAP in a brand new installation of Plone (adding LDAP
is literally the first step I have taken, and a requirement):

Version info:
* Plone 4.1.3 (4112)
* CMF 2.2.4
* Zope 2.13.10
* Python 2.6.7 (r267:88850, Feb 14 2012, 12:51:07) [GCC 4.6.2]
* LDAP Support version 1.2.7

I get the following error on save:

Exception Value
argument of type 'NoneType' is not iterable

Traceback (innermost last):

* Module ZPublisher.Publish, line 126, in publish
* Module ZPublisher.mapply, line 77, in mapply
* Module ZPublisher.Publish, line 46, in call_object

TypeError: argument of type 'NoneType' is not iterable

Any suggestions welcome.

I suggest to take the Python debugger in order to figure out further details
of your (local) problem. If this problem is not widely known that you need
to provide
further insight on issues (unless it can reproduced easily).
