Only persons in addressbook

How can I modify our addressbook that our users just see persons when they open the address dialogue in the client ?I tried to use reader fields to hide all groups and mail in records, but after that admin4 requests are not working properly and I am not sure what happens with the acl groups.

Maybe there is a solution with a apecial view ?

Subject: Only persons in addressbook

try to work with a new R6 functionnality : extended ACL. See admin help for more informations.With that you can hide elements from names to selected category of people.
