Binding FreeRadius to the DHCP Server

Thanks for the on-topic question, I was already fearing a flamewar coming up.

I guess if you really want to this, you could use rlm_perl or 
Exec-Program-Wait, write a script that uses the client's MAC address to 
generate a fake DHCP query (assumption: the DHCP server or a relay is on the 
FR server's LAN), listen to the DHCP server's response, encapsulate this 
answer back into the Framed-IP-Address attribute and that's it (leaving out 
all the really painful stuff with expiring leases, renewals and whatnot; it 
would be a non-trivial task).

The remaining question really is: Why on earth would you _want_ to do that? 
rlm_ippool exists and works.

Greetings,

Stefan
