[Zope] problem with LDAPUserFolder 1.5b1

Hi, I've installed openldap 2.0.23 on a server and a client and all seems to work fine (AFAICTAICTM) In Zope I've installed LDAPUserFolder 1.5b1 and I can see no group. I can see all users though. My users base DN is : ou=People,dc=my,dc=domain,dc=org My groups base DN is : ou=Group,dc=my,dc=domain,dc=org Both ZLDAPConnection and ZLDAPMethod seem to work ok. Since it's openlap and not Netscape's one I don't think the restictions mentionned in th README apply, but I really don't know much. any help appreciated. Jerome Alet
