Question IP assignment to authorized user only through DHCP server !!!


Hi to all linux experts,

Pls receive my greeting for the day !!!

I've a DHCP server in RHEL 5 and 100+ users in my network. I mapped 30 users MAC address with ip. Rest are getting ip address automatically. In my network, users tend to move from one department to another frequently. I've created scopes according to departments. (i.e. Dept A - 172.19.54.10-172.19.54.30 and so on for other departments).

1) I want to configure DHCP server in this way, that a client have to autheticated by DHCP server before receive and IP address.

2) Second, Whether DHCP server have free IPs in scope, but only clients can obtain IPs those MACs are mapped, rest should not without authentication or authorization.

Regards
Arunabh
