Closing as the AUTHORS files needs a real name for the contributor. If someone wants to pick this up feel free to take the code and submit a new pull request.

Real names are a requirement which has been there for ages. In Icinga 1.x it was not enforced that straight forward, but Icinga 2.x will do so by generating authors (and therefore copyright owners) from git history.

I personally still don't get the reason why you chose to hide behind an anonymous nickname, but it's your choice if you contribute to an open source project, or rather not. I'd be proud if someone accepts my patch in a project with my real name.
