Hello. OpenBSD and Free Radius

Hi all. I'm trying to install a Radius server into Open BSD for AAA for my lan users. Basically, i would like to offer username and password for each one of them. i hope to manage its bandwidth  too. i have the instructions for DHCP server, Firewall, but radius. i only has encountered openbsd as pppoe client and i would like to give AAA for my users. thanks a lot. -- Carlos Diego Raffaelli A
