kleides-dssoclient 0.9

Discourse Single-Sign-on (DSSO) provider client to connect your Django project to a Discourse Single-Sign-On provider server.

See: https://meta.discourse.org/t/official-single-sign-on-for-discourse-sso/

Example usage:

• Add kleides_dssoclient to INSTALLED_APPS.

• Create a custom DssoLoginBackend, for example:

  from kleides_dssoclient.backends import DssoLoginBackend
  
  class MyProjectDssoLoginBackend(DssoLoginBackend):
      """
      DssoLoginBackend that rejects anyone without is_superuser, and that
      sets all mapped variables on the newly created User object.
      """
      def authenticate(self, dsso_mapping):
          """
          Check that user is a superuser and pass along to DssoLoginBackend.
          """
          if dsso_mapping.get('is_superuser') not in ('True', 'true', '1'):
              return None
  
          return super(MyProjectDssoLoginBackend, self).authenticate(
              dsso_mapping)
  
      def configure_user(self, user, dsso_mapping):
          """
          We expect username, email, is_superuser in the dsso_mapping.
          """
          user = (
              super(MyProjectDssoLoginBackend, self)
              .configure_user(user, dsso_mapping))
  
          user.email = dsso_mapping.get('email', '')
          is_superuser = (
              dsso_mapping.get('is_superuser') in ('True', 'true', '1'))
          user.is_staff = is_superuser
          user.is_superuser = is_superuser
  
          user.save()
          return user

• Add this to the Django settings:

  AUTHENTICATION_BACKENDS = (  # the only backend needed
      'myproject.backends.MyProjectDssoLoginBackend',
  )
  MIDDLEWARE_CLASSES += (
      'kleides_dssoclient.middleware.DssoLoginMiddleware',
  )
  KLEIDES_DSSO_ENDPOINT = 'https://DSSOSERVER/sso/'
  KLEIDES_DSSO_SHARED_KEY = 'oh-sso-very-very-secret'
  KLEIDES_DSSO_CREATE_UNKNOWN_USER = True
