Authenticate to Django with JSON Web Tokens (JWTs) signed by Cloudflare Access. A Django reimplementation of https://developers.cloudflare.com/cloudflare-one/identity/authorization-cookie/validating-json/#python-example

To run the demo, set the following environment variables:

export ALLOWEDFLARE_ACCESS_URL=https://your-organization.cloudflareaccess.com
export ALLOWEDFLARE_AUDIENCE=64-character hexadecimal string
export ALLOWEDFLARE_PRIVATE_DOMAIN=your-domain.tld

Then run

docker compose up

Configure Cloudflare Tunnel public hostname demodj.your-domain.tld to http://localhost:8001 or equivalent.

• Iterate on the same-origin (re-)authenticating proxy
  • From-scratch reimplementation of https://developers.cloudflare.com/cloudflare-one/identity/authorization-cookie/cors/#send-authentication-token-with-cloudflare-worker
  • Setting username so it can be logged by gunicorn
  • Setting the XmlHttpRequest(?) header to avoid redirects to the sign-in page
• Iterate on Admin site ModelBackend
  • http://localhost:8001/admin/login/ text when authenticated is "You are authenticated as , but are not authorized to access this page. Would you like to login to a different account?"
• Expand unit test coverage
• Basic integration and end-to-end tests
• mTLS support and testing
• Configure PostgreSQL
  • Post-migration hook to create a readonly DB user
  • Use the readonly DB user for django-sql-explorer and jupyterhub
  • Update the django-sql-explorer allowlist to accept SET since it's only dangerous for MySQL
  • Exclude only specific fields, like password hash, from the django-sql-explorer view of the django.contrib.auth schema
  • See if admin site change history fields can be shown in the django-sql-explorer schema viewer

• Do existing projects like django-allauth or https://django-rest-framework-simplejwt.readthedocs.io/en/latest/index.html already provide this functionality?
• What about RemoteUserMiddleware?
• Are there Free/Libre/Open Source alternatives to Cloudflare Access and Okta that I can run end-to-end tests against?
