django-openid-auth OpenID失败：未知用户

Question

I'm trying to implement a simple single sign on Open ID authentication on Steam via django-openid-auth using Django 1.4.1 I basically used the same exact settings as provided in the official repo example :

import os
import django
import settings_local

DEBUG = True
TEMPLATE_DEBUG = DEBUG
PROJECT_DIR = os.path.dirname(__file__)

ADMINS = (
     ('me', 'me@gmail.com'),
)

MANAGERS = ADMINS

        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': settings_local.DB_NAME,
        'USER': settings_local.DB_USER,
        'PASSWORD': settings_local.DB_PW,
        'HOST': settings_local.DB_HOST,
        'PORT': '',
    }
}

STATICFILES_DIRS = (
    # Put strings here, like "/home/html/static" or "C:/www/django/static".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
)

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
#    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)

SECRET_KEY = settings_local.PROJECT_SECRET_KEY

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',

}

# django-openid-auth
AUTHENTICATION_BACKENDS = (

            'propagate': True,
        },
        }
    }

my views.py

    if request.user.is_authenticated():

    else:
        return render_to_response('home.html', {'auth_url': '/openid/login/'})

    return HttpResponse('?next= bit works')

@login_required

    return HttpReponse('This page requires authentication')

def login(request):
    pass

home.html

    you are {{ username }}
    {% endif %}

{% endif %}

What happens :

• user clicks on login
• redirected to steamcommunity.com/openid/login and asked steam id/pw
• redirected back to the website at /openid/complete/?janrain_nonce=... with a 403 error code, triggering django-openid-auth "unknown user" message code

What I have tried :

• using the django-openid-auth exemple and replacing OPENID_SSO_SERVER_URL by the Steam OpenID endpoint -- it works
• using this exemple repository and placing the Steam OpenID endpoint in /media/js/openid-en.js -- it works too

I can't find what is wrong in my code after searching for hours now.

EDIT : Fixed it. Simply took settings.py from django-openid-auth/example_consumer and changed it line by line to see where the problem was. Ended up having the exact same settings.py pasted on this page but it's now working...

Answer 1

I ran into the exact same issue and discovered that the problem was with this line:

OPENID_CREATE_USER = True

This setting is missing the S at the end of the name. The line should read:

OPENID_CREATE_USERS = True

Correcting this typo caused OpenID login to work perfectly. When the OP says "Ended up having the exact same settings.py pasted on this page but it's now working..." they probably missed this very small difference.
