Set environnement variable

[Alexandre DELAY]

Hi guys,

I'm using freeradius to authenticate users against PPP (Poptop and PPPOE).
After connection, i start a few processes from 
/etc/ppp/ppp.linkup and need
to set some user dependent variable.
I would like to get those informations from the same database as for auth.
Here is my question:

Is it possible to set environnement variables during 
authentication process?
Wth this, I will use them to launch my processes.

(my other solution is to setup a secured connection to the sql 
database, but I would like to use freeradius if possible).

Thanks for the help

cheers

Alex
