different sidebars on password protected page

I have a password protected page without a sidebar on the login page. Once a user has logged in then the sidebar is revealed. The code I use for this in the page template is:
<?php
if ( !post_password_required() ) {
include(TEMPLATEPATH . ‘/sidebar5.php’);
}
?>

I would now like to modify this and display a different sidebar on the login page for some general info. I have tried adding to the above:
else
{
include(TEMPLATEPATH . ‘/sidebar-password.php’);
}

Nothing happens though. It still works but the login page still doesn’t show the alternate sidebar.

Any ideas? Thanks in advance.
