I have some linux machines that I have configured for student

This is the problem I am having.   Any user with access to the
system can run the /usr/bin/finger command and do a name search
against our entire LDAP tree.   I would like to limit the info
available via finger to just the users that have access to any
particular machine.   How can this be controlled?

This sounds more like a firewall / iptables issue to your finger server than anything else ?

No, doesn't sound like that to me.

Essentially he wants an ACL that grants access to nss-ldap searches based on the target entries belonging to a group associated with a particular peeraddr. But at the moment, I can't think of any mechanism to do this in the current ACL engine.
