IP Pool defined, but radius does not hand out an IP address.

[Andrew D Kirch]

When I connect a client to freeradius the client authenticates, gets an
accept/accept, but does not get an IP address.  I've tried it with the
Group and Pool-Name directives in each client's block, and I've tried it
with them in a DEFAULT by themselves.  Neither has handed out an IP address.
