OpenID IDP for Google hosted domains

[Adam Griffiths]

Hi

I would like to get single sign on (SSO) working from a Google apps domain to a node.js project. For Google apps domains the discovery protocol is an extension of the normal OpenID approach. Has anyone looked into, or able to point me in the right direction for making it work with everyauth? 

I've been looking into doing the job with passport.js but not made it work yet. The kind of SSO I want to do is described here https://developers.google.com/google-apps/marketplace/sso. The Google extension to the discovery protocol is documented here https://sites.google.com/site/oauthgoog/fedlogininterp/openiddiscovery.

Thanks

Adam
