I set Freeradius with mysql server and Daloradius Management.
After some troubles to install FR, it worked fine, at least as basical startup: i can authenticate remote users!

OK.

For real it works if i use /raddb/clients.conf file, setting readclients = yes in /raddb/sql.conf.
Once i set it to "no", autentication fails. I checked nas table structure and it's ok, the same as in /usr/local/etc/raddb/sql/mysql/nas.sql
User are instead loaded fine from mysql users table.

Your message doesn’t have enough information to troubleshoot your problem. Run FreeRADIUS in debug mode (radiusd –X) and read the error messages. If you still can’t solve your problem, send the debug output to the mailing list.
