Why would you want to use an external script. If it's a fixed value per user then why not use files. Then have that match to the user and return the value you want. mods-config/files/authorize ---- test_user Framed-Pool := Foovalue ---- Then you call files when you need to. I tend to avoid calling external scripts as they are slow and if they crash or memory leak for whatever reason it can take down your whole server.

My file /etc/freeradius/users user_test Cleartext-Password := "testing" Auth-Type := Accept Framed-Protocol = PPP Framed-Pool = `%{exec:/bin/echo foo}` Fall-Through = Yes It's not working. What it's happening? Using the freeradius debug the Framed-Pool attribute is appearing empty. - List info/subscribe/unsubscribe? See http://www.freeradius.org/ list/users.html
