  <p>my question is I can the change the value to </p>
  
  <pre><code>&lt;endpoint address="http://localhost:.........svc"&gt;
                      &lt;identity&gt;
                          &lt;userPrincipalName value="other_someone@mydominio.com" /&gt;
                      &lt;/identity&gt;
                  &lt;/endpoint&gt;
  </code></pre>
