Did this ever get implemented? I find the error messages infuriatingly innacurate. For example, users who leave their browsers open so that their session expires are told their account has been locked, or sometimes that 'access to this version has been disabled', both of which are a lie. Simply attempting to log in again fixes the problem, but users don't know that, and they phone us administrators instead.
Please can you fix the login screen error messages and make them more accurate?
