Hi,
ci.linaro.org has switched the security realm from Launchpad OpenID to Crowd SSO. In practice, it means that authentication is using your regular login/password from login.linaro.org service.
In addition, the project authorization strategy has been switched to project-based matrix authorization strategy.
Those changes allows more permissions granularity at the project/job level. It is now possible to create private/restricted jobs or allow anonymous users to read your job configuration if you want.
