[Zope] Error with LDAPUserFolderExt

[Gitte Wange]

Hello,

I'm trying to setup a LDAPUserFolder inside GRUF. (It's my first attempt 
so).
When I'm trying to add the user folder, I get this error:

Exception Type  	TypeError
Exception Value 	__init__() got multiple values for keyword argument 
'local_groups'

Traceback (innermost last):

    * Module ZPublisher.Publish, line 98, in publish
    * Module ZPublisher.mapply, line 88, in mapply
    * Module ZPublisher.Publish, line 39, in call_object
    * Module Products.LDAPUserFolderExt.LDAPUserFolder, line 268, in 
manage_addLDAPUserFolderExt

TypeError: __init__() got multiple values for keyword argument 
'local_groups'

I'm not sure what this error means. I have looked at the code but can't 
really see what the multiple values should be - local_groups is a 
select-box.

Anyone with a hint ?

Greetings,
