Web Login Attempts

Hi, I need to limit the attemps a web user can do in order to gain access to his/her mailbox. For example, I don’t want a user to do more than 3 tries and then block the acoount or send a mail to the admin or something else, then will see. I saw DSAPI but I want to know if there are any other way to do this, maybe a third party product or a Notes.ini variable. Thanks in advance. Regards.
