[Samba] multi factor authentication

[Jason Keltz]

I was trying to research whether multi factor authentication is possible 
with Samba AD.  There's not that information out there. We have both 
Linux systems with Winbind authenticating from Samba AD and Windows 
systems authenticating via Samba AD.   I saw a message from Louis almost 
a year ago with some links, but as far as I can tell, not specifically 
tied to Samba AD (unless I misunderstood).  Rowland - you also mentioned 
the "freis-franken.org" link, but that doesn't exist anymore.  I'm not 
looking for LDAP-based proxy type solutions.  I'm looking for something 
that ties directly into winbind PAM module on Linux and on Windows.  I 
know if it's doable, someone is doing it.  :)

Thoughts?

Thanks,

Jason.
