Hasn't this been covered before?
Both are wontfix's, and I agree with the reasoning. Knowing if the
username is valid or not is not a security flaw. Security comes from
the system actually being secure, not whether or not somebody can work
out the usernames.
I mean, okay, I understand it in the case of other utilities. Look at
the old SSH documents, and yeah, a username leak makes it that much
easier to run a brute force attack. But this is not SSH. This is a
webpage with a login form. The same solutions should not instantly
apply just because that's what people think of as 'secure'.
What's the potential for harm here? What can somebody do knowing that
the username is wrong or the password is wrong? Brute force attack? If
we want to protect against brute force attacks, hiding the usernames
isn't the right way to do it. The right way there would be to
recognize rapid repeated failures to login from the same IP and block
that IP for a period of time.
I vote for closing #5301 as wontfix *unless* somebody changes the
thing to actually point to a potential exploit and not some
theoretical "you can't know the username" security-theater idea.
