将onethink和phpwind数据库安装在一起，使用通用的表前缀。

将onethink的member表指向phpwind有user表

以下为onethink安装在根目录下，phpwind安装在bbs目录下的情况

修改onethink中的is_login函数

function is_login(){
  $site=include('./bbs/data/cache/config.php');
  C('BBS_SITE_SET',$site['data']['site']);		
  if (!($userCookie = \Org\util\Pw::getCookie('winduser'))) {
      return 0;
  } else {
      list($uid, $password) = explode("\t", \Org\util\Pw::decrypt($userCookie));
      $user_session = session('user_auth');
      if (empty($user_session)||$user_session['uid']!=$uid) {
        //$user = new User\Api\UserApi();
        //$info = $user->info($uid);
        /* 记录登录SESSION和COOKIES */
        $auth = array(
          'uid'			 => $uid,
          'username'		=> get_username($uid),
          'last_login_time' => NOW_TIME,
        );
        session('user_auth', $auth);
        session('user_auth_sign', data_auth_sign($auth));
      }
      return $uid;
  }
/*
    $user = session('user_auth');
    if (empty($user)) {
      return 0;
    } else {
      return session('user_auth_sign') == data_auth_sign($user) ? $user['uid'] : 0;
    }
*/
}
