We have freeRadius for authentication on a Ubuntu box, but the DHCP allocation is handled elsewhere, specifically by a Win2012R2 DHCP server. Is it possible to configure freeRadius in such a way that the DHCP server gets a suitable "hint" (while still being the sole responsible server for actual ip allocation)?
What I mean with "hint" is that the Windows DHCP server can follow policies that evaluate specific options of a DHCP request:
- vendor class,
- user class,
- MAC address,
- client id,
- fqdn,
- relay agent information.
I suppose MAC better be left alone, and relay agent info seems to appply for the case of DHCPrelay. But maybe it is possible that freeradius can tell everybody authenticating there to request their IP with e.g. a user class that is under control of the radius server?
