When account lockouts are enabled, VSys can lock itself after too many failed login attempts.
If enabled, and the user has attempted this number of consecutive failures during the specified time period, VSys will lock out his account for the given number of days, hours, and minutes. This lock can be removed by right-clicking on his name in the Security manager and resetting the lockout.
Any successful login clears this failure count, although each and every failed attempt remains logged in this user's history.
