wifi / mac authentication

hello im using freeradius 1.02-4 (debian) if i have my access points set for mac address authentication via radius what settings do i require on the freeradius end? currently in my DB i have it setup as this groupname: Enabled Auth-Type :=Local Compression used: :=Van-Jacobsen-TCP-IP Service type: := Framed-User groupname: Disabled Auth-Type :=Reject Now when a wireless client trys to connect will the NAS sends the mac address and does it append the NAS password or do you supply a specific password for the mac address? when it authenticates the Wireless client will they have internet access (obtained ip/dhcp etc all thru the nas) or Rejected if in the disabled account (no internet access) Thanks
