I have installed Plone 4.2.1 and plone.app.ldap 1.3. If the ldap server is activated, the ldap user can login, but the admin cannot access the @@usergroup-userprefs page. It throws up some errors as follows:
Traceback (innermost last):

On disabling the ldap server, the admin can access the @@usergroup-userprefs page of the plone site.
OpenLDAP is also installed. When I run the command $dpkg -l|grep OpenLDAP, I get the follwing listing.
ii ldap-utils 2.4.23-7.3 OpenLDAP utilities
ii libldap-2.4-2 2.4.23-7.3 OpenLDAP libraries

ii slapd 2.4.23-7.3 OpenLDAP server (slapd)
If the LDAP entries with uid and SN attribute are not populated for some of the users,or the uid includes space before or after the uid value. On a whole this problem occurs if the ldap data is not correctly added, then the above users and groups sub-menu in plone throws up errors as above.
