> Is there any way to have a radius server assign the IP addresses to PPTP

yes. to do that, download the vpn.inc in /etc/inc and insert
	set iface enable radius-ip
before line 568¡£save && upload to mono and issue 'cp /tmp/vpn.inc /etc/inc'

now goto services->pptp, do nothing but press save. the mpd should
restart and ready to assign the ip address given by the radius server.
here i assume you have configured every other things, such as the
radius server, the address pool, etc.

and, mpd is so powerful that it can do more than that.  for example,
it can take the acls returned by the radius server and create/delete
ipfw pipes/queues/rules on per-user basis when users login/logout.

for more details, refer to the mpd documents.
