I'm using IMP for authentication (against IMAP). When modifing the user name in
vinfo hook can't login.
imp/lib/Session.php
line 101:

         if (!empty($conf['hooks']['vinfo'])) {
             require_once HORDE_BASE . '/config/hooks.php';
             if (function_exists('_imp_hook_vinfo')) {
                 $_SESSION['imp']['user'] = call_user_func('_imp_hook_vinfo');
             }
         }

line 114:
         if (Auth::isAuthenticated()) {
             $_SESSION['imp']['uniquser'] = Auth::getAuth();
         } else {
             $_SESSION['imp']['uniquser'] = $_SESSION['imp']['user'];

line 219:
        $auth_imp = &Auth::singleton(array('imp', $conf['auth']['class']));
        $auth_imp->authenticateOptions(array('flags' => OP_HALFOPEN));
        if ($auth_imp->authenticate(null, null, true) !== true) {
            return false;
        }

and later on in lib/Auth/imp.php uses $_SESSION['imp']['uniquser'] for
authentication agains IMAP.
        if (empty($userID)) {
            if (empty($_SESSION['imp']['uniquser'])) {
                return false;
            }
            $userID = $_SESSION['imp']['uniquser'];
        }
...
        $login = ($login && ($this->getProvider() == 'imp'));

        return parent::authenticate($userID, $credentials, $login);

What am I missing?
