You might find http://ux.stackexchange.com/a/25674/597 of interest ;)

In general locking accounts often causes more problems than it solves
in my experience. It many cases it turns cracking attacks into DOS
attacks as multiple users get locked out.

A better approach in my experience is to throttle the login attempts.
This kills bulk cracking attempts, lets valid users still login, and
prevents mass-lockouts that can cause major support/PR hassles.

Cheers,

Adrian
