Mac auth configuration

[Vineet Verma]

Hi,
    I have been able to configure FreeRadius to successfully 
authenticate a client based on the MAC address with entries like:

00-0c-41-5f-91-4b Auth-Type := Local, User-Password == "00-0c-41-5f-91-4b"
        Acct-Interim-Interval = 60

Is there any way to configure it so I don't have to list every client? 
For example can I have some kind of glob as follows, say for all clients 
with OUI 00-0c-41:

00-0c-41-* Auth-Type := Local, User-Password == "00-0c-41-5f-91-4b"
        Acct-Interim-Interval = 60

If not, how do I do something like this?

Thanks,
Vineet
