rlm_python: Access Request source IP Address is missing from authorize(p) function argument

[Gleb Lisikh]

Hi!

I'd like to be able to work in my python authorize function with the IP
address of the NAS interface from which Access-Request is received
(external). From the radiusd -X output this is the A1.A2.A3.A4 address I am
interested in.
=========================================
Received Access-Request Id 7 from A1.A2.A3.A4:54594 to B1.B2.B3.B4:1812
length 415
==========================================
This is the same IP address that gets tested against shared secret
configured in clients.conf

Unfortunately, the tuple (p) that gets passed to the authorize function
(authorize(p)) by rlm_python has a different (internal) NAS-IP-Address,
which is of no use to me.

If radiusd is in principle aware of the A1.A2.A3.A4  IP address I am
interested in, how can I gain  access to it in my python authorize(p) or
any other function?

Thank you,

Gleb
