Question about radiusclient

Hello All In the radiusclient configuration file there is an option called auth_order which accepts two values (local, radius). If we set this option as follows: auth_order radius,local doesn't it means that if the authentication fails using RADIUS it should be performed using the /etc/passwd file? In other words, if we define all those users, which are not mentioned as radius users, as local users of the machine where radiusclient runs, it should be OK. Is that right? I have tested the so-called scenario, but it does not work. Does anyone have any experiences regarding this issue? Warm Regards Ali Majdzadeh Kohbanani
