the user who logined by python-social-auth can't access the page that is only logined user.(Django)

Any user who registers on my homepage directly can access the homepage (which requires the user to be logged in). But a user who registers with python-social-auth can log in, but can’t @@access the homepage.

This is my settings.py

I have the same problem – I cant access views with login_required decorator (from django.contrib.auth.decorators) after logging through SteamOpenId. However if I login in django-admin then I can see there that user is successfully created/associated. What could I miss?

EDIT: Problem was gone after social.backends.steam.SteamOpenId was replaced with social_core.backends.steam.SteamOpenId.

Thanks @Nuqlear for the hint - this hit me as well. Maybe the configuration switch from to social_core.backends could get fixed in the docs here?

http://python-social-auth.readthedocs.io/en/latest/configuration/django.html#template-context-processors

That would be great!
