我成功安装了CAS4.1，并将其配置为使用Active Directory作为后端身份验证。现在的问题是，每次我尝试验证票证时CAS服务器都会抱怨票证过期。我获取和验证票证的步骤如下：

1. 呼叫https://sso.domain.net/cas/login?service=https：//myservice.domain.net
2. 我ST-2-NLOngMHayTl3uCLKn91T-sso.domain.net拿到一张票
3. 调用验证服务https://sso.domain.net/serviceValidate?ticket=ST-3-zrjAFf1UU95NdzGmCibv-sso.domain.net

我得到了以下回应：

<cas:serviceResponse xmlns:cas="http://www.yale.edu/tp/cas">
  <script/>
  <cas:authenticationFailure code="INVALID_TICKET"> 
   Ticket 'ST-3-zrjAFf1UU95NdzGmCibv-sso.domain.net' not recognized
  </cas:authenticationFailure>
</cas:serviceResponse>

我从这个StackOverflow条目中使用了相同的ticketOutirationPolicy. xml，我得到了相同的结果，我也尝试更改为根本没有过期，但得到了相同的结果我当前的ticketExirationPolicy.xml文件：

一个附带问题：我在哪里以及如何定义服务以充当代理？！
