Different DHCP Pools based on User

[Paul]

Hi,

is there some possibility to configure the following scenario:

We have multiple Users, say Alice and Bob and Charles (and many more).

All of them authenticate via a FreeRadius Server and need an IP via DHCP,

but Alice needs IPs from 10.1.0.0/24, Bob from 1xx.xxx.28.0/24 and 
Charles from 192.168.10.0/24.

I couldn't find an example of this or remotely similar scenarios.

Thanks in advantage!

Paul
