Why, just because we can! 🙂
If you want the user to be locked after unsuccessful logon attempts, you can put a parameter in the Instance Profile to prevent them from doing so.
Transaction RZ10–> Instance Profile–> Extended Maintenance
Use the ‘login/fails_to_user_lock’ Parameter.
Defines the number of unsuccessful logon attempts before the system locks the user. By default, the lock applies until midnight.
Default value: 12; permissible values: 1 -99
To remove the lock after midnight :
login/failed_user_auto_unlock: Defines whether user locks due to unsuccessful logon attempts should be automatically removed at midnight.
Default value: 1 (Lock applies only on same day); permissible values: 0, 1
