Now I want to do IMSI based authentication with radius. Please can anyone help me on how to do IMSI based authentication.

Just use IMSI (3GPP-IMSI? Calling-Station-Id?) as User-Name, then insert "Auth-Type := Accept" line for that username into radcheck table: insert into radcheck(username, attribute, op, value) values ('255019501234567', 'Auth-Type', ':=', 'Accept'); -- With best regards, xrgtn
