I have a question here http://serverfault.com/questions/670436/how-do-i-use-tls-https-using-dane-dnssec IMO it's incorrectly marked as a duplicate. One question explains the problem and the expected results. The other was poorly worded and confused readers into locking it because they didn't understand it. Why are we locking both so no answers are possible? If you read both you'll see they are different questions trying to solve the same question and not a phrasing or a duplicate.
