django-admin-oauth2

A django app that replaces the django admin authentication mechanism by deferring to an oauth2 provider.

Support

django-admin-oauth2 should support Python 2.7, pypy, and Django versions 1.6 through 1.10

Installation

Step 1: pip install django-admin-oauth2 and include it in your project's requirements

Step 2: Include the django-admin-oauth2 urlconf in your project's urls.py:

url(r'/admin/oauth/', include('oauthadmin.urls'))

Step 3: Include oauthadmin in your INSTALLED_APPS:

INSTALLED_APPS = (
    'oauthadmin'
)

Step 4: Install the middleware in your project's settings.py:

MIDDLEWARE_CLASSES = (
    'oauthadmin.middleware.OauthAdminSessionMiddleware'
)

make sure that this comes AFTER 'django.contrib.sessions.middleware.SessionMiddleware'

Step 5: If you are on Django 1.5 or above, you'll need to set your session serializer to "django.contrib.sessions.serializers.PickleSerializer" since we are storing the pickled user object in the session.

SESSION_SERIALIZER = "django.contrib.sessions.serializers.PickleSerializer"

Step 6: Set up all the correct options (see below for available options)

Settings

• OAUTHADMIN_GET_USER: This is function that is given the oauth token and returns a django.auth.models.User model corresponding to the currently logged-in user. You can set permissions on this user object and stuff.
• OAUTHADMIN_CLIENT_ID: Your oAuth client ID
• OAUTHADMIN_CLIENT_SECRET: oAuth client secret
• OAUTHADMIN_BASE_URL: The landing point for all oAuth related queries.
• OAUTHADMIN_AUTH_URL: oAuth provider URL
• OAUTHADMIN_TOKEN_URL: oAuth bearer token provider URL
• OAUTHADMIN_PING_INTERVAL (optional, defaults to 300): Minimum number of seconds between ping requests
• OAUTHADMIN_PING: (optional, defaults to None) This optional function takes an oauth token and returns True if it's still valid and False if it's no longer valid (if they have logged out of the oauth server)
• OAUTHADMIN_DEFAULT_NEXT_URL: (optional, defaults to /admin). This optional value is the default page that a successful oauth login process will land you on.
• OAUTHADMIN_SCOPE: (optional, defaults to ['default']). This is a list of authorization scopes.

Testing

If you want to test this app, install the requirements needed for testing:

pip install -r test-requirements.txt

and then run the tests with the provided script:

./runtests.sh

Notes

When the CSRF validation token doesn't match, django-admin-oauth2 will redirect back to the login url so it can retry the authorization step. Sometimes people will bookmark the oauth server with an out-of-date CSRF state string, this is better than showing them an error page.
