 * When users have different passwords based on the host from which they connect
 MariaDB MaxScale is unable to determine which password it should use to connect
 to the backend database. This results in failed connections and unusable
 usernames in MariaDB MaxScale.

+For example, a netmask of 255.255.255.0 is fine while 255.255.255.192 is not.
