title: Custom sfGuard login redirect not working in symfony
body: <p>I am using Symfony 1.4.8 and Propel as ORM. I have created a custom Sfguard login by creating a SfGuardAuth. 
  I have created a login form in some pages which are not secure(i.e which are public) and want that on login, it should start a login session. 
  the code that i am using, </p>
  
  <pre><code>$this-&gt;signin = new sfGuardFormSignin(); //creating form object
  </code></pre>
  
  <p>in view</p>
  
  <pre><code>&lt;form action="&lt;?php echo url_for('@sf_guard_signin') ?&gt;" method="post"&gt;
     &lt;table&gt;
         &lt;?php echo $signin; ?&gt;
     &lt;/table&gt;
     &lt;button type="submit"&gt;submit&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>and also configured app.yml in (app/frontend/modules/mymodule/config/app.yml) because i wanted this for this specific module only.</p>
  
  <pre><code>all:
    sf_guard_plugin:
      success_signin_url: mydashboard/index
      success_signout_url: goodbye/index
  </code></pre>
  
  <p>but on login it redirects to symfonys temporary module i.e <a href="http://localhost:8080/frontend_dev.php/" rel="nofollow">http://localhost:8080/frontend_dev.php/</a></p>
  
  <p>so what can be done?</p>
