The use of TLS also encrypts all traffic between the +clients and the KDC, preventing observers from conducting password +dictionary attacks or from observing the client and server principals +being authenticated, at additional computational cost to both clients +and servers.</p> +<p>An HTTPS proxy server is provided as a feature in some versions of +Microsoft Windows Server, and a WSGI implementation named <cite>kdcproxy</cite> +is available in the python package index.</p> +<div class="section" id="configuring-the-clients"> +<h2>Configuring the clients<a class="headerlink" href="#configuring-the-clients" title="Permalink to this headline">¶</a></h2> +<p>To use an HTTPS proxy, a client host must trust the CA which issued +that proxy’s SSL certificate.
