Keystone SSO
This was just a branch off of master. We're not using the Federated path,
but we are using SSO (it'd be nice if we could make this a separate setting)
"""Logs a user in using a token from Keystone's POST."""
referer = request.META.get('HTTP_REFERER')
auth_url = re.sub(r'/auth.*', '', referer)
- request.federated_login = True
+ request.federated_login = False
request.user = auth.authenticate(request=request, auth_url=auth_url)
auth_user.set_session_from_user(request, request.user)
auth.login(request, request.user)
From 2da7cf44b6f78c28a0b7706b28dc733146810df8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] * add a new auth mechanism called InferredDomain that will
load the user regardless of domain * sso working in keystone using the
remote provider * Update the url for the return call to live under the
