Terminate the Session after unsuccessful logon:

If you want to prevent unsuccessful logon attempts before the system does not allow any more 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_session_end' Parameter.
Default value: 3; permissible values: 1 -99

Note: The parameter is to be set to a value lower than the value of parameter login/fails_to_user_lock.
