WordPress HTTP API NTLM Authentication

In case anyone has issues like I did, I found this discussion where I added the code and instantly was authenticated. Not sure if its a WordPress issue or a PHP one, but I feel that the ANY portion of the WordPress authentication was getting blocked first to find the Proxy type, but timing out. Adding the code from this link worked: https://core.trac.wordpress.org/ticket/31232#comment:7

add_action( 'http_api_curl', function( $handle ) {
    curl_setopt( $handle, CURLOPT_PROXYAUTH, CURLAUTH_BASIC );
});
