      Interesting finds Jonas, and a good writeup. Were these issues among those rejected for bounty?

      How long do you think it took to make that group policy exploit? Finding the right vulnerabilitis to chain to make it all work. But because another vuln took 1 year to fix- the service was in a state where all submissions are waste of time for researchers.
