I have configured two RADIUS servers for authentication (see attached picture). Despite the priority configuration and the Round-Robin setting (see other picture), it seems the controller send Accounting packets to both servers.
I tried to disable strict mode and configured the RADIUS in the WLAN section (see third picture). The behaviour is the same.
This causes me problem as each RADIUS server (FreeRADIUS instance) hosts a MySQL database for accounting records. Both DBs being replicated in Master-Master, the simultaneous arrival of accounting packets from the controller to both RADIUS servers causes the replication to crash (as entries with same Accounting-Session-Id are inserted on each database).
I have noticed that the Round-Robin setting is for Authentication only. Is there a way to do the same for Accounting as well ?
Thanks in advance for your help.
