authenticating to an Windows AD

[Mike Diggins]

Folks, I have freeradius running on a fedora linux box. I want to use it 
for authentication from an Apache web server using the radius interface. 
That part is working, and I'm able to authenticate web users only if they 
have a local account on the freeradius server.

I want freeradius to authenticate against a Windows Active Directory. I 
installed Samba and am running Winbind, and wbinfo/ntlm_auth both are able 
to authenticate from the command line assuming I give it a valid username 
and password. What module in freeradius do I use to authenticate through 
Winbind? Could someone point me in the right direction please.
