title: Proxy authentication for Azure CLI
body: <p>For the Azure CLI, is there a way to use proxy authentication? Our proxy servers needs all requests to be authenticated and I do not see any document relating. Using HTTP_PROXY environment variable, I can instruct the az cli to use a particular proxy server but I cannot define it to use proxy authentication, OR if there is a way to do this, I do not know. Our Proxy authentication has to be done either through NTLM or Kerberos.</p>
  
  <p>Can the relevant team, please check If we can configure az cli to use Kerberos proxy authentication?</p>
