title: Testlink-Track Integration issue
body: <p>I have done the following to integrate Testlink with TRAC, but i couldn't able to integrate.
  Testlink version - 1.9.9(lone ranger)
  TRAC version - 0.12.5</p>
  
  <p>I have edited the /var/www/testlink/cfg/trac.cfg.php file:</p>
  
  <pre><code>/** Trac Project Root */
  define('BUG_TRACK_DB_HOST', 'http://172.16.9.137/trac/');
  define('BUG_TRACK_XMLRPC_HOST', 'http://admin:admin@172.16.9.137');
  
  /** @var array Mapping TL test project name vs trac project url */
  $g_interface_bugs_project_name_mapping = array(
       'Expresso' =&gt; 'expresso',
  );
  </code></pre>
  
  <p>and then edited the Edit /var/www/testlink/custom_config.inc.php file and added:</p>
  
  <pre><code>&lt;?php
       $g_interface_bugs = 'TRAC';
  ?&gt;
  </code></pre>
  
  <p>then i was asked to edit the Edit /var/www/testlink/lib/bugtracking/int_trac.php file and replace:</p>
  
  <pre><code>$this-&gt;xmlrpcClient = new IXR_Client($this-&gt;dbHost . '/xmlrpc');
  by
  $this-&gt;xmlrpcClient = new IXR_Client(BUG_TRACK_XMLRPC_HOST);
  </code></pre>
  
  <p>but i couldn't find <strong>/bugtracking/int_trac.php</strong>
  I followed the steps from "<a href="http://lfestivalet.wordpress.com/2012/09/27/part-5-testlink-trac-integration/" rel="nofollow">http://lfestivalet.wordpress.com/2012/09/27/part-5-testlink-trac-integration/</a>"
  what is the correct way to integrate testlink 1.9.9 with TRAC 0.12.5?</p>
