WP_FAIL2BAN_AUTH_LOG

New in version 2.2.0.

By default, WPf2b uses LOG_AUTH for logging authentication success or failure. 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_AUTH_LOG', LOG_AUTHPRIV);
