CVE-2018-6188: Information leakage in AuthenticationForm

A regression in Django 1.11.8 made AuthenticationForm run its
confirm_login_allowed() method even if an incorrect password is
entered. This can leak information about a user, depending on what
messages confirm_login_allowed() raises. If confirm_login_allowed()
isn't overridden, an attacker enter an arbitrary username and see if
that user has been set to is_active=False. If confirm_login_allowed()
is overridden, more sensitive details could be leaked.

This issue is fixed with the caveat that AuthenticationForm can no
longer raise the 'This account is inactive.' error if the
authentication backend rejects inactive users (the default
authentication backend, ModelBackend, has done that since Django
1.10). This issue will be revisited for Django 2.1 as a fix to address
the caveat will likely be too invasive for inclusion in older
versions."
