New in version 4.4.0.

By default, WPf2b uses LOG_AUTH for logging various events. However, some systems use LOG_AUTHPRIV instead, but there’s no good run-time way to tell. If your system uses LOG_AUTHPRIV you should add the following to wp-config.php:

define('WP_FAIL2BAN_USE_AUTHPRIV', true);


This only changes the default use of LOG_AUTH - it doesn’t override individual settings.
