我没有使用过phpwind ，所以也不太清楚，不过以下是在piwigo里的一些配置说明，希望对你有帮助吧：

// All informations contained in these tables and column are related to
// piwigo_users table.
$conf['users_table'] = $prefixeTable.'users';

// If you decide to use external authentication
// change conf below by $conf['external_authentification'] = true;
$conf['external_authentification'] = false;

// Other tables can be changed, if you define associated constants
// Example:
//   define('USER_INFOS_TABLE', 'pwg_main'.'user_infos');

// user_fields : mapping between generic field names and table specific
// field names. For example, in PWG, the mail address is names
// "mail_address" and in punbb, it's called "email".
$conf['user_fields'] = array(
  'id' => 'id',
  'username' => 'username',
  'password' => 'password',
  'email' => 'mail_address'
  );
