Q:contact lists/address books schemas?

["Axel Eble" <Axel.Eble@GMX.DE>]

Hi there,

I understand this has been asked and addressed every now and then, but I did
not find answers in the archives that did help me...
anyway, I plan to manage my business contacts and addresses in my LDAP
server. Now to make good use of them I understand they should in some way be
associable to the users of my organization, like with an attribute like
"onContactListOf: dn-of-user-of-my-org".

Is this a useful idea or would you suggest other ways of dealing with
objects that are not directly related to the organization the directory
server is responsible for?

Kind regards,
    Axel
