FreeRadius fault by exec

[Anton Kiryushkin]

Hello.

I am trying to use exec and I am receiving the next log on version 3.0.15:

and output 'Auth-Type = Accept'

Could you please where am I wrong?

The exec is simple:

exec py-exec {
        wait = yes
        input_pairs = request
        output_pairs = reply
program = "/local/pyexec/pyexec.py --user=%{User-Name}
--key=%{User-Password}"
        shell_escape = yes
}
