How create NTLM Authentification with Retrofit
<p>Since 23 sdk Android class were excluded classes:</p>

<pre><code>org.apache.http.auth.AuthScheme;
org.apache.http.auth.AuthSchemeFactory;
org.apache.http.impl.auth.NTLMScheme;
org.apache.http.impl.auth.NTLMEngine;
org.apache.http.impl.auth.NTLMEngineException;
</code></pre>

<p>As it is now authorized in AD, with login and password through a retrofit? There OKHttpklient can be through headers?</p>
