MAC or user auth

[CoMeC]

Hi,

I try to configure such a solution:

Authorization via MAC Address (with no username required) - if the machine
is using a valid IP Address, it is automatically allowed to surf.
(I know there is a Calling-Station-id attribute in radcheck)


But I need also a support for username/password authentification (via WWW)
too.

When I try to log in only with MAC, I get a Radius responce "no username",
and the machine is denied.

How/where in radiusd.conf can I make changes?

Thx in advance,

Best regards,

CoMeC
