User-based lockout compliance

When a specified number of unsuccessful authentication attempts has occurred, remote users can be locked out. If the system-configured usernames (manager, operator, and local users) are not unique, the user-based lockout delay feature cannot be enabled. If lockout-delay with the user-based-lockout feature is enabled, the manager, operator, or local user creation fails for duplicate usernames. Locked out users are unlocked after reboot.
