我已经安装了一个带有公共域的 CAS 服务器，它可以正常工作。
现在我想通过 CAS 身份验证将我的其他公共域与不同的服务一起使用，但是，在登录 CAS 后，当我重定向到这些服务时，PHPCas 告诉我“身份验证失败，您没有经过身份验证”
我已经搜索了很长时间，但找不到任何解决方案。我需要的是保持两台服务器之间的 CAS 会话。
PHPCas认证的配置是：
phpCAS::client(CAS_VERSION_2_0,'example.com', 8443,'/cas', TRUE);
网址是这样的：http://client.com/portal.php?ticket=ST- ..... 所以票证被授予（在 CAS 服务器日志中告诉“票证被授予”），为什么认证失败？
这里有 phpCAS 的日志：

我已将真实 URL 更改为 XX，只是为了保护隐私 :) 我能做什么？谢谢！
