title: Override a translation on the Sonata Admin login screen
body: <p>On the Sonata Admin login screen the default translation is "Authentication", but i'd like to be able to change this.</p>
  
  <p>Inside <code>\vendor\sonata-project\user-bundle\Resources\views\Admin\Security\login.html.twig</code> there is this line:</p>
  
  <p><code>&lt;div class="header"&gt;{{ 'title_user_authentication'|trans({}, 'SonataUserBundle') }}&lt;/div&gt;</code></p>
  
  <p>The translation for this is found in <code>\vendor\sonata-project\user-bundle\Resources\translations\SonataUserBundle.en.xliff</code>, i.e.:</p>
  
  <pre><code>        &lt;trans-unit id="title_user_authentication"&gt;
              &lt;source&gt;title_user_authentication&lt;/source&gt;
              &lt;target&gt;Authentication&lt;/target&gt;
          &lt;/trans-unit&gt;
  </code></pre>
  
  <p>I am trying to work out how I can change this from within my own bundles. This scenario doesn't appear to be covered in the Sonata documentation, which is very good.</p>
