Directory assistance - What if not every user has access to all the addressbooks?

Hi Folks,

One of our customers has multiple Addressbooks on his Servers. One of these Adressbooks should not be accessible to all the Users (Management-Contacts).

All these Adressbooks are configured in the da.nsf.

It all works fine, but when a User who has no access to the managementadressbook wants to do anything that searches the addressbooks (like looking for reciepents), he gets an error reporting that he has no access to the managementadressbook.nsf.

How can I tell these clients not to search this addressbook?

Thank you very much!

Michael
