Hi All, I have configured freeradius. So after finish configuration when i started i got this error. Aug 28 15:21:59 radius3 freeradius[7330]: /etc/freeradius/sites-enabled/default[405]: Failed to find "sql" as a module or policy. Aug 28 15:21:59 radius3 freeradius[7330]: /etc/freeradius/sites-enabled/default[405]: Please verify that the configuration exists in /etc/freeradius/mods-enabled/sql. Aug 28 15:21:59 radius3 freeradius[7330]: /etc/freeradius/sites-enabled/default[273]: Errors parsing authorize section. Aug 28 15:21 I modified these linesin this file. sudo nano /etc/freeradius/mods-available/sql login = "freeradius" server="localhost" port=3306 password = "radius123" and uncommented read_clients = yes and client_table="nas" change database table configuration: radius_db="radius" and also in sudo nano /etc/freeradius/sites-enabled/default file all 4 sections(authorize,accounting,session,post-auth) sql are uncommented. What am I missing? Any suggestion highly appreciated
