Bug 902412

It only tries to do that if you're upgrading the package. You would only be doing that if you had previously installed OpenShift. A previous install of OpenShift and this package wouldn't be very useful if you haven't configured authentication, meaning creating that file. I don't think there's much risk anyone will see this error. Perhaps for the future the condition could also check that the file exists.

So there's a harmless error message if the plugin is installed but not enabled (i.e., there is .conf.example but not .conf for this particular plugin), right? I don't think it would be unusual at all to have all the auth plugins installed with only one of them enabled.  We should probably follow Luke's last suggestion and simply check that the file exists before executing the sed command.

Yes, you are right.

Sorry, I thought I had posted this earlier.  Here's a pull request with the suggested fix: https://github.com/openshift/enterprise-server/pull/28
