Proxying Machine Authentications

[King, Michael]

I currently have our wireless users authenticating to our Active
Directory 2003 domain using PEAP and TTLS.

We want to proxy our machine authentications off to something else that
can authenticate them.

Does anyone have any examples of how to do this?

I know all the machine accounts show up on my NAS as 

host/machinename

Whereas my users are :

Domain\Username 
Or
Username
