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

[ryulstory]

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

How do you check if somebody has access to that page? Also, why is the next value different for form-login and social-login?
