Authenticate to Jupyterhub using an authenticating proxy that can set the REMOTE_USER header.

This project folder must be on your PYTHONPATH. You should edit your jupyterhub_config.py to set the authenticator class:

c.JupyterHub.authenticator_class = 'remote_user.RemoteUserAuthenticator'

You should be able to start jupyterhub. The "/login" resource will look for the authenticated user name in the HTTP header "REMOTE_USER". If found, and not blank, you will be logged in as that user.
