This works by having a single Identify Provider that hosts your credentials and a number of Service Providers that exchange encrypted messages with the Identity Provider in order to validate your identity when you connect. OpenID is the underlying protocol that implements this exchange of messages in a standard way so that any OpenID Service Provider can accepts credentials from any OpenID Identity Provider. In the context of Ubuntu, U1 is an OpenID Service Provider (and presumably Identity Provider too) so can accept OpenID authentication messages to validate your identity. > > So, assuming my explanation above was clearer than mud and with it in mind, what probably happens is that the browser attempts to authenticate with the service using OpenID. For some reason, the service has an issue with the way the OpenID request is sent or with its content.

Got this message too. I decided that it meant I had not yet created an open id account, so I put a password in etc etc and that seemed to do the trick. I think that having a U1 sign on is not quite the same as also having a open id (also known as single sign on, I think.....) >> >> Can anyone help to confirm this please? >> >> --
So, a reporable bug to ubuntu-one?
