Can’t login by using ClaimID

I get a certificate error when I try to login today.

I see that there are other questions on a similar topic, but they appear to be older. This looks like a new problem.

When I press the login button on this screen:

  • Are you trying to use https:// to access the site? That's not supported. Commented Nov 20, 2012 at 15:24
  • I am pressing the login button on this page productivity.stackexchange.com/users/login Commented Nov 20, 2012 at 15:28
  • Which button? You need to be more explicit, there are several there. Can you give us the actual error? Commented Nov 20, 2012 at 15:42
  • The "Log in" button, it points to this link: productivity.stackexchange.com/users/authenticate Commented Nov 20, 2012 at 20:28
  • Oh hey, claimid. I've seen that around a few times lately...

  • Perhaps claimid redirects back to a https url instead of the correct http url. Commented Nov 20, 2012 at 20:55
  • @ShirazBhaiji Are you able to login using CLAIMID now? I contacted them and they said they believe the issue has been resolved. It looks like the certificates have been setup correctly now but I dont have a claimid to test with.

  • @droid, thanks for the help. My browser refreshed and I got a "wellcome back" without having to log in. Claimid still has a problem, the name on the certificate does not match the url. You can see it if you go to this address: openid.claimid.com/login the cert is for claimid.com, the address is openid.claimid.com Commented Nov 27, 2012 at 22:13

No, theres no problem with any Stack Exchange certificates. The problem is Clamid's. You can recreate the issue by hitting their login site directly as well.

Im no SSL expert, but it doesnt look like they have a wildcard SSL certificate, namely it looks like their certificate is only good for claimid.com and not for openid.claimid.com. This appears to be a recent change, as they moved from claimid.com to openid.claimid.com before and now it seems they are reverting (or simply messed up their certificate setup).

According to the certificate dates, it looks like they requested a new certificate (or a renewal) last Friday (11/16/2011). That is, in all likelihood, when the issues began.
