The problem addressed in patch PHNE_12161 as implied in the description,
only fixed a problem of not updating the bad login counter. This _does_
fix the vulnerability issue, however on successful log ins the bad login
counter _does_not_ get cleared, therefor locking the users out no matter
how many times they login successfully between unsuccessful attempts.

So to your reply I respectfully add:

This problem _has_NOT_ been fully addressed in patch PHNE_12161. It
only addressed the most severe part of the problem, leaving an
administrative headache. If you consider the administrator who's work
load can't handle the added stress of constantly reactivating a number
users, he may opt to disable this feature once again leaving the system
vulnerable.

I have patch PHNE_12161 applied and I'm constantly reactivating user
accounts do to this problem. I have confirmed the problem it is
reproducible and is a major headache. This is still a very big problem!
