We make use of nginx subrequests to block media file downloads while
we check for access rights. The request is then proxied to the object
storage engine and authorization is added via the "Authorization"
header. This way the media urls are static and can be stored in the
document's json content without compromising on security: access
control is done on all requests based on the user cookie session.
Integrate 'mozilla-django-oidc' dependency, to support
Authorization Code flow, which is required by Agent Connect.
Thus, we provide a secure back channel OIDC flow, and return
to the client only a session cookie.
Done:
- Replace JWT authentication by Session based authentication in DRF
- Update Django settings to make OIDC configurations easily editable
- Add 'mozilla-django-oidc' routes to our router
- Implement a custom Django Authentication class to adapt
'mozilla-django-oidc' to our needs
'mozilla-django-oidc' routes added are:
- /authenticate
- /callback (the redirect_uri called back by the Idp)
- /logout
