title: proFTPd + tls authentificatin issue
body: <p>Can't get in my ftp server. I use proftpd 1.3.4a with mod_tls/2.4.3.</p>
  
  <p>I suspect a mistake lies it the <strong>TLSOptions</strong> directive</p>
  
  <pre><code>TLSEngine                        on
  TLSLog                           /var/log/proftpd/tls.log
  TLSProtocol                      SSLv23
  TLSRSACertificateFile            /etc/proftpd/ssl/proftpd.cert.pem
  TLSRSACertificateKeyFile         /etc/proftpd/ssl/proftpd.key.pem
  TLSOptions                       NoCertRequest EnableDiags NoSessionReuseRequired
  TLSVerifyClient                  off
  TLSRequired                      on
