Apache Auth via User/OTP fails

[Vogt, Andreas]

Hello,

I try to authenticate via my Apache Webserver to my freeradius Server.
The Apache connects successful, and provides User/OneTimePassword to the freeradius.

Here I use the following Config:
Auth-Type OTP_OWA {
update control {
           SECRET := `/usr/bin/php /freeradius_scripts/getSecretFromDB.php --username=%{User-Name} `
LAST_USED_PIN := `/usr/bin/php /freeradius_scripts/get_last_used_pin.php --username=%{User-Name}`
PIN := `/bin/bash /freeradius_scripts/getPin %{control:SECRET}`
PIN_FROM_USER := %{User-Password}
ATTEMPTS := `/usr/bin/php /freeradius_scripts/get_attempts.php --username=%{User-Name}`
Auth-Type :=     `/usr/bin/php /freeradius_scripts/check_pin_dev_log.php --username=%{User-Name} --pin=%{control:PIN} --pin_from_user=%{User-Password} --last_used_pin=%{control:LAST_USED_PIN} --attempts=%{control:ATTEMPTS}`
                }
     }

Unfortunately I receive an REJECT from the freeradius:
{DEBUG Output}:

So my .php Script checks the OTP-PIN ans returns “Accept”, but the freeradius answers Accept-Reject… Why?

Thanks for any response 😉
