On the other hand...

Be aware that attackers can use the lockout feature to cause a denial of service attack. If I don't like you, I can just set up a script that fails to log in as you over and over again, and you'll just be locked out all the time.

Having the lockout only last 15 minutes is good, but still vulnerable. One of the systems where I work actually disables your account after X failed logins and we have to call an admin to get re-activated. Very very bad...

You have to decide which is worse the vulnerability of letting someone try 20,000 logins or the vulnerability of making it easy to lock your users out.
