Auth and QuickForm usage problem ?!

hi all, i'v try to used Auth-1.2.3 and QuickForm 3.2.4pl1 to generate login form, but i've a little problem with applying custom filter. It's not a QF usage problem: i know this package, but i don't think it's such easy to use (its filter feature) with Auth package. If i'm not wrong (please someone, tell me) the Auth::start() method run the Auth::assignData() that set POST data just before QF may validate the form (and apply filters). So it's to late, and data are assigned with no-filtered form datas Here are the most important code of my script: My platform: PHP 4.3.10, PEAR 1.3.4, Windows XP, Apache 1.3.3 Is someone may help me to understand if it's a wrong Auth package usage or if it's a bug ? Thanks in advance Laurent Laville <?php // my QF custom filter function filterSecure($values) {

    $values = trim($values);
    $values = strip_tags($values);
    return $values;

} function loginFunction($username, $status, &$auth) {

    require_once 'HTML/QuickForm.php';
    require_once 'HTML/QuickForm/Renderer/QuickHtml.php';

    $form = new HTML_QuickForm('dauth');
    [....]
    $form->applyFilter('__ALL__', 'filterSecure');
    [....]

    $renderer = new HTML_QuickForm_Renderer_QuickHtml();
    $form->accept($renderer);

    $html_template = '

................ the form template itself ...... ';

    echo $renderer->toHtml($html_template);
    $form->validate();

} $storageDriver = 'File'; $options = 'passwd.file'; $loginFunction = 'loginFunction'; $a = new Auth($storageDriver, $options, $loginFunction); $a->start(); if ($a->checkAuth()) {

    echo 'welcome '.$a->getUsername();

} ?>
