Hi there,

As I understand it the first configured RADIUS server configured under the WLAN will be used for authentication. The second will only be used when the first times out. The default timeout is 10 seconds.

As long the RADIUS servers have been added to their respective AD domains or have been authenticated using LDAP, there should be no issues with authentication.

Does this help?

The primary RADIUS server (the server with the lowest server index) is assumed to be the most preferable server for the controller. If the primary server becomes unresponsive, the controller switches to the next active backup server (the server with the next lowest server index). The controller continues to use this backup server, unless you configure the controller to fall back to the primary RADIUS server when it recovers and becomes responsive or to a more preferable server from the available backup servers.
