      Description

      This may not be a bug, exactly, but it would be nice if the failure behavior was more graceful.

      We have the OpenID plugin configured to authenticate Jenkins users using our corporate domain on Google Apps for Business. Jenkins knows its internal URL as hudson.ourdomain.com:8080, a legacy of the pre-Jenkins days. We also have some alias URLs, like jenkins.ourdomain.com:8080 and jenkins.ourdomain.com on port 80 running through an Apache redirect/proxy.

      When I turned on the Google Apps OpenID authentication, I found that it worked fine if you logged in from the "real" Jenkins domain/page, but if you connected via one of the alias URLs and clicked "log in," you got an NPE.

      Here's the stacktrace:
