The maximum number of times that a user can attempt to log in with an incorrect password before the user account is locked out. The number specified for the lockout period after maximum login failures determines how long the user account is locked out. Accounts that are locked cannot be used to gain access to the system even if a valid password is provided. The maximum value is 10 times. The default value is 5 times. A value of 0 means that accounts are never locked.
