Freeradius + DHCP +vlans ???

[George Beitis]

Hey guys
I am a bit new to the scene and i am having a few problems with
configuring freeradius.  In essence what i want is that the user, once
verified to be assigned to a specific vlan and get an ip address from a
dhcp server, which will be aware of the vlans and there for assign
different address and subnets to each.  Does this scenario make any
sense?  Will it be the freeradius server that will be notifying the dhcp
server to aquire an address for the client?  Will the dhcp server then
contact the access point to let it know what address the client has been
given and it in its turn give it to the client?  Or will it be that the
access point will contact the dhcp server once it has the reply from the
freeradius server, giving it the vlan id/number and requesting an ip
address and other info?

Is this the right or wrong way of going about this?

George
