CAS 4.0 服务管理 Web 应用程序 - 应用程序无权使用 CAS

谁能帮我，因为我真的不明白 CAS（新手）。我有网址http://localhost/program/phpcas/CodeIgniter-3.0.6/，如果有人访问该网址，则应在http://localhost:8080/cas中重定向/使用 SSO CAS。

但是我遇到了麻烦，如果我访问http://localhost/program/phpcas/CodeIgniter-3.0.6/我从 cas 收到消息错误：

应用程序无权使用 CAS

您尝试进行身份验证的应用程序无权使用 CAS。

这是CAS代码：

        This file lets CAS know where you've stored the cas.properties file which details some of the configuration
        options
        that are specific to your environment. You can specify the location of the file here. You may wish to place the
        file outside
        of the Servlet context if you have options that are specific to a tier (i.e. test vs. production) so that the
        WAR file
        can be moved between tiers without modification.

以下是 PHPCAS 为此 url 使用 CI3 ：

配置/CAS.php

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$config['cas_server_url'] = 'http://localhost:8080/cas';
$config['phpcas_path'] = 'application/libraries/phpcas/source';
$config['cas_disable_server_validation'] = TRUE;

图书馆/CAS.php

<?php

function cas_show_config_error(){
    show_error("CAS authentication is not properly configured.<br /><br />
    Please, check your configuration for the following file:
    <code>config/cas.php</code>
    The minimum configuration requires:
    <ul>

拜托，如果你知道如何解决它，你能告诉我吗？
