• Free software: BSD License
• Homepage: https://github.com/snok/django-auth-adfs
• Documentation: http://django-auth-adfs.readthedocs.io/

Features

• Integrates Django with Active Directory on Windows 2012 R2, 2016 or Azure AD in the cloud.
• 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 received from ADFS.
• Django Rest Framework (DRF) integration: Authenticate against your API with an ADFS access token.

Installation

Python package:

pip install django-auth-adfs

In your project's settings.py add these settings.

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

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

# checkout the documentation for more settings
AUTH_ADFS = {
    "SERVER": "adfs.yourcompany.com",
    "CLIENT_ID": "your-configured-client-id",
    "RELYING_PARTY_ID": "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",
    "CA_BUNDLE": "/path/to/ca-bundle.pem",
    "CLAIM_MAPPING": {"first_name": "given_name",
                      "last_name": "family_name",
                      "email": "email"},
}

# Configure django to redirect users to the right URL for login
LOGIN_URL = "django_auth_adfs:login"
LOGIN_REDIRECT_URL = "/"

########################
# OPTIONAL SETTINGS
########################

MIDDLEWARE = (
    ...
    # With this you can force a user to login without using
    # the LoginRequiredMixin on every view class
    #
    # You can specify URLs for which login is not enforced by
    # specifying them in the LOGIN_EXEMPT_URLS setting.
    'django_auth_adfs.middleware.LoginRequiredMiddleware',
)

In your project's urls.py add these paths:

urlpatterns = [
    ...
    path('oauth2/', include('django_auth_adfs.urls')),
]

This will add these paths to Django:

• /oauth2/login where users are redirected to, to initiate the login with ADFS.
• /oauth2/login_no_sso where users are redirected to, to initiate the login with ADFS but forcing a login screen.
• /oauth2/callback where ADFS redirects back to after login. So make sure you set the redirect URI on ADFS to this.
• /oauth2/logout which logs out the user from both Django and ADFS.

You can use them like this in your django templates:

<a href="{% url 'django_auth_adfs:logout' %}">Logout</a>
<a href="{% url 'django_auth_adfs:login' %}">Login</a>
<a href="{% url 'django_auth_adfs:login-no-sso' %}">Login (no SSO)</a>
