Authentication does not work

See original GitHub issue

When I tried to do an initial setup of the application based on the documentation, I came across this error when trying to sign in to dashboard:

Internal Server Error: /dashboard/login/

AttributeError: 'WSGIRequest' object has no attribute 'strip'

I am using Django 1.11 and in settings:

AUTHENTICATION_BACKENDS = (
    'oscar.apps.customer.auth_backends.EmailBackend',
    'django.contrib.auth.backends.ModelBackend',
)

OK, got it.

The problem is in the EmailBackend.authenticate method, since there is one argument missing - request.

Instead of authenticate(self, email=None, password=None, *args, **kwargs) it should be authenticate(self, request, email=None, password=None, *args, **kwargs)

because of this calling line:

File "/home/eshop/env/lib/python3.5/site-packages/django/contrib/auth/forms.py", line 187, in clean
    self.user_cache = authenticate(self.request, username=username, password=password)
