Multiple Django apps, shared authentication

Question

Two answers to this question, depending on whether sharing is across different sites or different subdomains Second answer: Multiple Django apps, shared authenticati

Answer 1

As Sudipta mentioned, openid is one way to accomplish SSO.

Another way is to use SAML directly (there are some tools out there for this), or a hosted service like Stormpath (https://stormpath.com) which does SSO stuff for you, and provides directly support with Django's auth system: https://github.com/stormpath/stormpath-django

I work at Stormpath, so pretty biased, but figured I'd chime in as there's quite a lot of confusion around regarding SSO + Django solutions.
