Hi, As mentioned here before, there is a project underway to add support for OAuth & OpenID to Zinc HTTP Components and thus to Pharo Smalltalk as well. Zinc-SSO as the project is called is not yet finished but we would like to share some alpha code and our live demos: based on Jan van de Sandt's earlier CloudforkSSO work, we now have OAuth2 basically working. Partial documentation can be found here https://github.com/svenvc/docs/blob/master/zinc/zinc-sso-paper.md The document includes pointers to the repository where the development takes place. Note that the document itself is far from finished. This is not a subject where loading some code gives you a working demo since there is some setup to be done. Therefor we orginanized two live demos: http://sso.stfx.eu http://sso.doit.st Both allow you to use your existing Google, Facebook or Microsoft credentials (username/password) to authenticate and login to a simple demo web application. You actually grant the Zinc SSO Demo application access to view some of your basic user data - since the demo application then receives that grant it knows that you are the owner of that identity and that it can thus use it as a login. Also, as your browser probably stays logged in to the larger provider, this effectively comes down to single sign on (SSO). The first demo is running on top of Zinc only, the second demo uses Seaside for its user interface. Both use the same Zinc-SSO-OAuth2-Core code, Zinc HTTP Components, Zodiac and NeoJSON. Regards, Jan & Sven PS: We would like to thank Andy Burnett of Knowinnovation Inc and ESUG for sponsoring this open source work. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
