The following is an example of how the account lockout feature works.
An HDX system is configured with these settings:
• System > Admin Settings > General Settings > Security > External
Authentication is enabled.
• System > Admin Settings > General Settings > Security > Account
Management > Lock Account after Failed Logins is set to 4.
A user fails to log in to the Admin account twice on the web interface, and the
same or another user fails to log in to the Admin account on the local interface.
This means that three failed attempts have been made to the Admin account
so far. If the next attempt to log in to the Admin account on any login port is
unsuccessful, which would mean four failed logins, further attempts to access
the Admin account are locked out until the expiration of the Account Lock
Duration in Minutes period has elapsed. As this example illustrates, the failed
login attempts made to an account accumulate across any login port.
