We made the announcement at JavaOne that Sun was going to deploy an OpenID Identity Provider just for our employees and it went live last night. I have already created a few OpenID identifiers and verified their use. I'm pretty sure Sun is the first company to set up an employee only OpenID IdP. Very cool!

If you are interested in learning more about our deployment - of course we used our own products! - you can read more here or check out this helpful FAQ.
