If you select this option, a Framework fatal error will be initiated when a user has exceeded the number of allowed sign on attempts.
How Framework fatal errors are handled will depend on how the Framework has been set up, but usually the Framework will send an email to the administrator and then shut down. Any subsequent attempts to sign on as the same user profile after restarting the Framework will result in the same action.
To re-enable this user profile, the administrator must deselect the User Is Disabled checkbox for this user in the User Details tab.
This property is in the Framework User Administration Settings tab.
