3.3 Django settings

Make sure the following libraries are added to your INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    "django_better_admin_arrayfield",
    "django_auth_adfs",
    "django_auth_adfs_db",
    "solo",
    ...
]

Add mozilla_django_oidc_db.backends.OIDCAuthenticationBackend to the AUTHENTICATION_BACKENDS, this backend replaces mozilla_django_oidc.auth.OIDCAuthenticationBackend:

AUTHENTICATION_BACKENDS = [
    ...
    "mozilla_django_oidc_db.backends.OIDCAuthenticationBackend",
    ...
]

Ensure that LOGIN_REDIRECT_URL and LOGOUT_REDIRECT_URL are configured. For example:

LOGIN_REDIRECT_URL = reverse_lazy("admin:index")
LOGOUT_REDIRECT_URL = reverse_lazy("admin:index")

To enable validation of ID tokens by renewing them, add mozilla_django_oidc_db.middleware.SessionRefresh to the middleware, this middleware replaces mozilla_django_oidc.middleware.SessionRefresh:

MIDDLEWARE = [
    # middleware involving session and authentication must come first
    ...
    "mozilla_django_oidc_db.middleware.SessionRefresh",
    ...
]

Furthermore, ensure the following settings are configured:

OIDC_AUTHENTICATE_CLASS = "mozilla_django_oidc_db.views.OIDCAuthenticationRequestView"
MOZILLA_DJANGO_OIDC_DB_CACHE = "oidc"
MOZILLA_DJANGO_OIDC_DB_CACHE_TIMEOUT = 1

MOZILLA_DJANGO_OIDC_DB_CACHE is used to cache the configuration that is stored in the database, to prevent a lot of database lookups. Ensure this cache is configured in CACHES (using the backend of choice):

CACHES = {
    "default": {"BACKEND": "django.core.cache.backends.locmem.LocMemCache"},
    ...
    "oidc": {"BACKEND": "django.core.cache.backends.locmem.LocMemCache"},
}

Add the urlpatterns:

urlpatterns = [
    ...
    path("oidc/", include("mozilla_django_oidc.urls")),
    ...
]

Add the login link to your templates:

{% get_solo 'mozilla_django_oidc_db.OpenIDConnectConfig' as oidc_config %}
{% if oidc_config.enabled %}
<div class="submit-row">
    <a href="{% url 'oidc_authentication_init' %}">{% trans "Login with OIDC" %}</a>
</div>
{% endif %}
