title: `Server not found in Kerberos database` for DNS
body: <p>I have DNS over four ad-servers. When I'm trying to connect to DNS to validate Kerberos ticket I see this error: <code>Server not found in Kerberos database</code>. But when I connect to single ad-server directly I don't have any errors. Does anyone know what the reason might be? And how to connect to DNS without this errors? Thank you a lot!</p>
  <p>P.S. Algorithm for DNS is round-robin</p>
