FR Using MAC Authentication

Hi - 

I have just started tinkering with Freeradius, I built an Ubuntu 8.10 server box and installed FR --> sudo apt-get install freeradius*. It installed in a breeze and tested fine. I have setup a HP420 AP for testing, it's chattering with the FR box fine (I think). 

I want my wireless clients to do MAC authentication via the FR box. I have setup my users file to auth two of my test laptops: 

000E35-84610A Auth-Type := Local, User-Password == "esradius" 
00215C-08B25D Auth-Type := Local, User-Password == "esradius" 

When either tries to connect up, in the FR debug I see: 

rad_recv: Access-Request packet from host, id=7, length=53 
User-Name = "00215c-08b25d" 
User-Password = "00215c-08b25d" 
Processing the authorize section of radiusd.conf 

The authentication eventually fails: 

rlm_pap: WARNING! No "known good" password found for the user. Authentication may fail because of this. 

Why is the User-Password the MAC address and not what is specified in the users file? I have only tweaked the users and clients.conf files. 

Just simple MAC authentication, that's all I want at this point. 

Thanks in advance!
