The openID provider, used to log in to openqa.opensuse.org, is currently down.
As we switched other services to the new IDM system already, we decided to not bring the old provider back. We are instead working on a new implementation, which allows to use the new IDM as backend.
We apologise for the inconvenience caused, but the problem only affects a handful of people. openQA itself is up and running. Only special logins are affected - and this is hopefully fixed at the end of the week.
Update: There is now a new openid provider at https://id.opensuse.org - not perfect but working well enough for openQA.
