freeradius eam sim authorization to everyone

Hello, I use freeradius 2.2.0 (runs on Ubuntu). I played enough with eap sim, (thanks for examples eapsim-02 - 06). My goal is to test client + AP but not freeradius authorization/authentication process. Ho can I configure freeradius to give success for every user, no matter what is imsi, challenge, kc or sres. Can I configure to give "OK" to any sim based on provider only, like "Orange", for example/ Thank you,
