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窶冲 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 窶弋his account is inactive.窶� 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.

Bugfixes:
Fixed incorrect foreign key nullification if a model has two foreign keys to the same model and a target model is deleted.
Fixed a regression where contrib.auth.authenticate() crashes if an authentication backend doesn窶冲 accept request and a later one does.
Fixed crash when entering an invalid uuid in ModelAdmin.raw_id_fields
