django-auth-adfs 0.2.0

A Django authentication backend for Microsoft ADFS

ADFS Authentication for Django

A Django authentication backend for Microsoft ADFS

Features

  • Integrates Django with Active Directory through Microsoft ADFS by using OAuth2.
  • Provides seamless single sign on (SSO) for your Django project on intranet environments.
  • Auto creates users and adds them to Django groups based on info in JWT claims received from ADFS.

Installation

Python package:

pip install django-auth-adfs

In your project’s settings.py

AUTHENTICATION_BACKENDS = (
    ...
    'django_auth_adfs.backend.AdfsBackend',
    ...
)

INSTALLED_APPS = (
    ...
    # Needed for the ADFS redirect URI to function
    'django_auth_adfs',
    ...

# checkout config.py for more settings
AUTH_ADFS = {
    "SERVER": "adfs.yourcompany.com",
    "CLIENT_ID": "your-configured-client-id",
    "RESOURCE": "your-adfs-RPT-name",
    # Make sure to read the documentation about the AUDIENCE setting
    # when you configured the identifier as a URL!
    "AUDIENCE": "microsoft:identityserver:your-RelyingPartyTrust-identifier",
    "ISSUER": "http://adfs.yourcompany.com/adfs/services/trust",
    "CA_BUNDLE": "/path/to/ca-bundle.pem",
    "CLAIM_MAPPING": {"first_name": "given_name",
                      "last_name": "family_name",
                      "email": "email"},
    "REDIR_URI": "https://www.yourcompany.com/oauth2/login",
}

# OPTIONAL SETTINGS

TEMPLATES = [
    {
        ...
        'OPTIONS': {
            'context_processors': [
                # Only needed if you want to use the variable ADFS_AUTH_URL in your templates
                'django_auth_adfs.context_processors.adfs_url',
                ...
            ],
        },
    },
]

MIDDLEWARE = (
    ...
    # With this you can force a user to login without using
    # the @login_required decorator for every view function
    #
    # You can specify URLs for which login is not forced by
    # specifying them in LOGIN_EXEMPT_URLS in setting.py.
    # The values in LOGIN_EXEMPT_URLS are interpreted as regular expressions.
    'django_auth_adfs.middleware.LoginRequiredMiddleware',
)

# Or, when using django <1.10
MIDDLEWARE_CLASSES = (
    ...
    'django_auth_adfs.middleware.LoginRequiredMiddleware',
)

In your project’s urls.py

urlpatterns = [
    ...
    # Needed for the redirect URL to function
    url(r'^oauth2/', include('django_auth_adfs.urls')),
    # If you're using Django 1.8, this code should be used instead
    url(r'^oauth2/', include('django_auth_adfs.urls', namespace='django_auth_adfs')),
    ...
]

The URL you have to configure as the redirect URL in ADFS depends on the url pattern you configure. In the example above you have to make the redirect url in ADFS point to https://yoursite.com/oauth2/login
