django-auth-adfs 1.3.1

A Django authentication backend for Microsoft ADFS and AzureAD

ADFS Authentication for Django

A Django authentication backend for Microsoft ADFS and Azure AD

• Free software: BSD License
• Homepage: https://github.com/jobec/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>

Fixed

• Fix retries towards ADFS in situations where ADFS didn’t respond in time.

1.3.0 - 2019-11-01

Note

From this release onwards, compatibility with python 2.7 and 3.4 is not guaranteed anymore.

Removed

• Python 2.7 and 3.4 tests
• Django Rest Framework 3.7 tests

Changed

• Python 3.8 tests
• Django Rest Framework 3.10 tests

1.2.0 - 2019-03-01

Removed

• Django 1.8, 1.9 and 1.10 support. They are end of extended support and keeping support for them was becoming too complex.

Fixed

• The django templates were missing in the wheel

1.1.2 - 2018-12-11

Added

• Added views to selectively disable SSO for login links

Fixed

• Existing users with an empty password raised an exception

• Fix fields in log messages being swapped.

Security

• Don’t allow the audience claim to be ignored. Preventing access token reuse.

1.0.0 - 2018-12-05

This version contains backwards incompatible changes. Make sure to read the entire release notes

Added

• Windows 2016 (a.k.a. ADFS 4.0) Support
• AzureAD support (check the setting TENANT_ID)
• Django Rest Framework support.
• Add a RETRIES and TIMEOUT setting for requests towards the ADFS server.
• Add the CLIENT_SECRET setting to support client secrets in the OAuth2 Flow.
• Users are now redirected back to the page that triggered the login instead of the main page.
• Groups a user belongs to can now be automatically created in Django (check the MIRROR_GROUPS setting)

Changed

• Django 2.1 support
• All settings that can be determined automatically are now set automatically
• When a claim mapped to a non-required field in the user model is missing, a warning is logged instead of an exception raised

Incompatible changes

• Because of the login and logout views that were added, the redirect URI back from ADFS should now point to /oauth2/callback. Keeping it at /oauth2/login would have caused a potential redirect loop.

Deprecated

  • AUTHORIZE_PATH
  • LOGIN_REDIRECT_URL
  • ISSUER
  • REDIR_URI
  • SIGNING_CERT
  • TOKEN_PATH

• By default, the ADFS signing certificate is loaded from the FederationMetadata.xml file every 24 hours. Allowing to automatically follow certificate updates when the ADFS settings for AutoCertificateRollover is set to True (the default).
