I created https://code.djangoproject.com/ticket/26401
> Since the usage of any of the backends requires models I used the ModelBackend with no issues in Django 1.8 (without auth in INSTALLED_APPS). So that is the place I want to refactor. I'm trying to write a regression test for this, but I can't think of a good way to do it. Essentially, I want to ensure django.contrib.auth.context_processors/middleware/backends can be imported if django.contrib.auth is not in INSTALLED_APPS. Using `override_settings(INSTALLED_APPS...)` doesn't "undo" the imports, so importing the modules again won't trigger an exception. Any ideas?
