Remove user manually using data manager

[ukostin]

Need script for removing users from db.
What's wrong ?

<?php

define('VB_AREA', 'External');
define('SKIP_SESSIONCREATE', 1);
define('SKIP_USERINFO', 1);
define('CWD', '/blabla/forum');
require_once(CWD . '/includes/init.php');

$user =& datamanager_init('User', $vbulletin, ERRTYPE_ARRAY);
$exist = array('userid' => 12345); // 12345 - existing user id in user table
$user->set_existing($exist);
var_dump($user->delete()); // $user->delete() returns int(0), nothing deleted

?>
