Yes, that's right.

The usual solution is to implement a rewriting function that would
create a unique NAS-Port ID from another pieces of information in the
request. This approach is described in section 10.2.4 "Rewriting Incoming
Requests" of the documentation (available online at
http://www.gnu.org/software/radius/manual/html_node/Rewriting-Incoming-Req
uests.html).

The examples/ directory contains some working samples, which might help
you implement your own rewriting procedure:

  examples/cisco.rw: function cisco_pid, called from cisco_fixup.
  examples/c3620.rw: function c3620_decode, called from c3620_fixup.
  examples/ascend.rw: function max_decode_port, called from max_fixup.

If you need any further help, please do not hesitate to write.

No, of course it does not. It has no way of doing so: there is no 
general interface which would connect to NAS and tell it to drop a line.

Radzap is a last resort utility for bringing the system database in
synch with the actual state of user pools. It operates only on
rad[wu]tmp files. Normally, you rarely need to use it, if at all.
