EAP-Type = SIM

Hi everybody, I'm trying to configure EAP-SIM test on my FreeRADIUS server, and I would like to know if is possible to validate the parameters by database as setting in the radcheck? I tested validating with the users file and all sounds good, but I'm not having the same results with just database configuration. It not recognises SIM EAP-Type, instead it returns MD5 value. Someone could help me to validate this parameters just using databases attributes? Thanks
