Using a Backup Server¶

The RADIUS Authentication App can be configured to use a backup server in case the primary is unavailable. The app will use the backup server if the primary does not authenticate the user.

If a secret is not defined for the backup server, then the secret from the primary server will be used instead.

You can determine if the backup server is being used by examining the logs with the sourcetype "radius_auth". The following log message will return logs indicating that the backup server is being used:

index=_internal "Authentication to secondary RADIUS server" sourcetype="radius_auth"
