server restricion in Open Directory

I will describe a little scenarion here so you can see where i’m having a bit of confusion with OD.

We are planning to setup an OD here at work with large number of users. We are entering several server records in this OD as well. Of course gropus are being created for users.

My question is basically with groups and servers connected to the OD. Is there a way to limit access to server A to everyone in the OD except for grroup A only? The option seems to be there, in the permission tab for the server record entered. However, any other user can connect. We basically would like 0 access to anyone else except for the group that has been allowed.

If this is not clear, i can provide more specifics.

Thanks in advacend to anyone wanting to help.

Xay.
