I'm running server versions of Confluence, Jira, Bamboo, and Fisheye/Crucible, with Crowd providing SSO. Is it possible to configure all the servers to use a common login page? The Atlassian products integrate well together, appearing almost as a single application, but the user experience is different depending on which login page they first hit. Can I make it so all the applications use the login for one of the other applications? Like Jira or Confluence?
