User + Password + AMC address group authentication

[Aaron Jansen]

Dear all,

I would like to do the following:

For a user FreeRADIUS should check the user name, password, and the MAC
address. The MAC address can be one of many in a list stored in a
database. So, this is not about a single user logging in on only one
device. 

I have taken a look at the rad(group)check table, but it seems that ALL
attributes should check out alright for the user to be authenticated.
So, I cannot just simply add a list of all possible user/MAC
combinations. 

How can I best achieve this? Any help would be appreciated. 

Best regards, 

Aaeron Jansen
