How to restrict the users using AD?

Hi,

I have following structure in my AD:

OU: Accounts

|- OU: User

 |- User 1

 |- User 2

 |- User 3

|- OU: Groups

 |- Accounting

 |- Production

 |- Jabber

User 1 is in the group Accounting, User 2 is in the group Production. Both users are also in group Jabber. I want to realize that only Users that are members of Jabber are shown in the contactlist. User 3, who is not a member of Jabber, should not be shown in the contactlist.

Any hint how I can realize that?

Greets, Chris
