Comment form showing even when logged in!

Hi,

I have this problem: even when I am logged in, I still need to enter my name, email, etc. before sending a comment.

How to arrange this?

Here is my code:

<?php
/**
 * @package WordPress
 * @subpackage cdharrison
 */

// Do not delete these lines
	if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if ( post_password_required() ) { ?>
		<p class="nocomments">This post is password protected. Enter the password to view comments.</p>
	<?php
		return;
	}
?>

<!-- You can start editing here. -->

<?php if ( have_comments() ) : ?>
	<h3 id="comments"><?php comments_number('Aucun commentaire', 'Un commentaire', '% commentaires' );?> agrave; “<?php the_title(); ?>”</h3>

	<ol class="commentlist">
	<?php wp_list_comments(array('avatar_size'=>32)); ?>
	</ol>

	<div class="navigation">
		<div class="alignleft"><?php previous_comments_link() ?></div>
		<div class="alignright"><?php next_comments_link() ?></div>
	</div>
 <?php else : // this is displayed if there are no comments so far ?>

	<?php if ('open' == $post->comment_status) : ?>
		<!-- If comments are open, but there are no comments. -->

	 <?php else : // comments are closed ?>
		<!-- If comments are closed. -->
		<p class="nocomments">Comments are closed.</p>

	<?php endif; ?>
<?php endif; ?>

<?php if ('open' == $post->comment_status) : ?>

<div id="respond">

<h3><?php comment_form_title( 'Laissez un commentaire', 'Laissez un commentaire &agrave; %s' ); ?></h3>

<div class="cancel-comment-reply">
	<small><?php cancel_comment_reply_link(); ?></small>
</div>

<?php if ( get_option('comment_registration') && !$user_ID ) : ?>
<p>You must be <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?redirect_to=<?php echo urlencode(get_permalink()); ?>">logged in</a> to post a comment.</p>
<?php else : ?>

<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">

	<?php if ($user_ID) : ?>

	<p>Vous &ecirc;tes connect&eacute; en tant que <a href="<?php echo get_option('siteurl'); ?>/wp-admin/profile.php">
		<?php echo $user_identity; ?></a>. <br /><a href="<?php echo get_option('siteurl'); ?>/wp-login.php?action=logout" title="Se d&eacute;connecter">Se d&eacute;connecter</a>.
	</p>

<?php else : ?>	

<p><input type="text" name="author" id="author" value="<?php echo $comment_author; ?>" size="22" tabindex="1" <?php if ($req) echo "aria-required='true'"; ?> />
<label for="author"><small>Nom <?php if ($req) echo "(required)"; ?></small></label></p>

<p><input type="text" name="email" id="email" value="<?php echo $comment_author_email; ?>" size="22" tabindex="2" <?php if ($req) echo "aria-required='true'"; ?> />
<label for="email"><small>Courriel (ne sera pas publi&eacute;) <?php if ($req) echo "(required)"; ?></small></label></p>

<p><input type="text" name="url" id="url" value="<?php echo $comment_author_url; ?>" size="22" tabindex="3" />
<label for="url"><small>Site web</small></label></p>

<?php endif; ?>

<!--<p><small><strong>XHTML:</strong> You can use these tags: <code><?php echo allowed_tags(); ?></code></small></p>-->

<p><textarea name="comment" id="comment" cols="100%" rows="10" tabindex="4"></textarea></p>

<p><input name="submit" type="submit" id="submit" tabindex="5" value="Soumettre" />
<?php comment_id_fields(); ?>
</p>
<?php do_action('comment_form', $post->ID); ?>

</form>
</div>

<?php endif; // If registration required and not logged in ?>

<?php endif; // if you delete this the sky will fall on your head ?>

Thanks!
