Django Federated Login

Django Federated Login provides an authentication bridge between Django projects and OpenID-enabled identity providers. The bridge is pre-wired to be used with a single Google Apps domain, but could be extended to be linked with other OpenID providers also. It is different from other OpenID consumers as this consumer only allows connecting to a pre-defined identity provider.

The provided backend matches users based on the e-mail address returned from the identity provider. If no matching user could be found, a user account can optionally be created.

I would love to hear your feedback on this package. If you run into problems, please file an issue on GitHub, or contribute to the project by forking the repository and sending some pull requests.

Compatible with Django 1.4, 1.5 and 1.6 on Python 2.6, 2.7, 3.2 and 3.3. Python 3 is supported through the python3-openid fork.

Installation

Installation with pip:

$ pip install django-federated-login

Add 'federated_login.auth_backend.EmailBackend' as authentication backend:

settings.py:
AUTHENTICATION_BACKENDS = (
    'federated_login.auth_backends.EmailBackend',
    'django.contrib.auth.backends.ModelBackend',
)

Add 'federated_login' as installed app:

settings.py:
INSTALLED_APPS = (
    ...
    'federated_login',
)

Provide the Google Apps domain to identify against:

settings.py:
FL_APPS_DOMAIN = 'webatoom.nl'

For Django 1.6, need to configure session serializer:

settings.py:
SESSION_SERIALIZER = 'django.contrib.sessions.serializers.PickleSerializer'

Register the views:

urls.py:
url(r'^federated/', include('federated_login.urls')),

Sync or migrate your database:

python manage.py syncdb
# or if you use South:
python manage.py migrate federated_login

Usage

Point your browser to /federated/login/. You might want to include a button to this url on the regular login page. You could also use the federated login page as the default login page, replacing the username and password login pages. To do this, configure the LOGIN_ settings:

settings.py:
LOGIN_REDIRECT_URL = '/'
LOGIN_URL = '/federated/login/'

Settings

These are the customizable settings:

FL_APPS_DOMAIN

Google Apps domain to identify against. Can be overriden by FL_SSO_ENDPOINT.

FL_USER_FACTORY (Default: 'federated_login.user_factories.normal')

Function that is called when creating a user account. Set to None to disable creation of new users. There is also 'federated_login.user_factories.staff' that creates staff users and 'federated_login.user_factories.superuser' that creates superusers.

FL_SSO_ENDPOINT (Default: Google Apps)

Override this setting to link with another OpenID identity provider. The FL_APPS_DOMAIN setting will have no effect when providing a custom FL_SSO_ENDPOINT.

FL_USER_CLASS (Default: 'django.contrib.auth.models.User')

Django model class to used to create and query for users.

FL_PATCH_ADMIN (Default: True)

Django's admin site is automatically patched to use federated login. Set this setting to False to disable this feature. You can call federated_login.admin.patch_admin() and federated_login.admin.unpatch_admin() to respectively patch and unpatch the admin site.
