[Zope] LDAPUserFolder and roles/groups assignment Problem

Wed May 11 05:21:11 EDT 2005

Hi ,

I've instantiated a Group User Folder object for my Zope+Plone 
application and configured it to take users from an LDAP server in order 
to get users id and passwords validated against LDAP. So far, so good 
users can log in using their LDAP credentials.

The underlying users’ source is a LDAPUserFolder. I have configured it 
so that the groups are not stored on LDAP. Consequently the groups' 
source is default UserFolder.I have also configured Anonymous,Member as 
default roles to LDAP users.

I'm using ZOPE (ver.Zope 2.7.5-final, python 2.3.5, linux2) and Plone 
(2.0.4.3)with GRUF version: 3.1.1 and LDAPUserFolder 2.4 on Debian box.
All except LDAPUserFolder installed from debian packages.

I have encountered problems with assigning other roles to users. When I 
enter acl_users/Users tab of my Plone site check one of the users and 
the role I want to assign, confirm it I get the following error:
********************

*************************************************

I get similiar error message when I try to assign a user to any group.

Another problem is that I sometimes when I click on the Users' tab I get 
a list of users who already logged in, sometimes I get no users and I 
have to use separate link to force their retrieval (there is a message: 
"It is reported that 106 users stand in the various user sources.It 
might be very long to retreive the whole list but you can force it by 
Clicking here.").

Has anybody any idea how to get this things to work? I must be able to 
assign Reviewers role to some of my users, otherwise nobody would be 
able to publish anything....
