Ubuntu launch single sign on service
Canonical has announced that it is unifying the login process for Ubuntu and Canonical related sites into the OpenID based Ubuntu single sign on. The new single and centralised login service will replace existing Launchpad logins, but as part of the transition, current logins will continue to work. Canonical plans to build on the OpenID component of the single sign-on service to enable the company to first integrate it's own sites and then to work with community managed sites to migrate them to the new service.
Launchpad users will find their account data shared with the Ubuntu single sign on process, allowing them to use the same credentials on both services; once the transition is complete this sharing will turned off. The code behind the service is not being published as open source, but Canonical say it is built with open source technology such as Python, Django, Apache and Postgres.
