title: Joomla does not redirect to login page with correct redirection parameters
body: <p>I have integrated Joomla with a vBulletin and a CPG using jFusion for my upcoming site for Cancer patients .</p>
  
  <p>I have set the login link of vB and CPG as <a href="http://fakesite.com/site/index.php?option=com_user&amp;view=login&amp;return=Zm9ydW0ucGhw" rel="nofollow">http://fakesite.com/site/index.php?option=com_user&amp;view=login&amp;return=Zm9ydW0ucGhw</a> , so that when a user logs into Joomla from that link , he will get redirected back to vB or CPG after a successful login .</p>
  
  <p>This is happening correctly when I login with a correct combination of user credentials , but when I login with a wrong username and password , it just redirects back to vB or CPG without any warning, or prompting to try to login again .</p>
  
  <p>The proper behavior should be = </p>
  
  <ol>
  <li><p>User logs in with incorrect username/pass </p></li>
  <li><p>Gets redirected to Joomla login page with correct login redirect parameter 
  That is , if he was accessing login form with this (index.php?option=com_user&amp;view=login&amp;return=Zm9ydW0ucGhw ) he should be redirected to it with the correct value of return parameter .</p></li>
  <li>After successful login , he she should would go to vB or CPG .</li>
  </ol>
  
  <p>I am using latest Joomla 1.5.x version .</p>
  
  <p>How can I fix this ?
  Please help me out , I've been on many forums , but nobody replies .</p>
