I'm using JIRA On Demand with Atlassian Cloud.
My users authenticate with Google Apps. Since early today, anyone who has logged out can no longer login. They get an authentication error from the login console.
I can see from the version history on my instance that the JIRA version was upgraded from V6.5 to V7.0 during yesterday.
Does anyone have any more info on this? Have opened support ticket but no response as yet.
