CAS 票证验证总是失败

Question

我成功安装了 CAS 4.1 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已过期。我一直在做的获取和验证票的步骤如下：

1. 致电https://sso.domain.net/cas/login?service=https://myservice.domain.net
2. 我收到了一张类似 ST-2-NLOngMHayTl3uCLKn91T-sso.domain.net 的票
3. 调用验证服务https://sso.domain.net/serviceValidate?ticket=ST-3-zrjAFf1UU95NdzGmCibv-sso.domain.net&service=https://myservice.domain.net

我得到以下回复：

<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>

我使用了来自 StackOverflow entry 的同一个 ticketExpirationPolicy.xml 我得到了相同的结果，我也尝试更改为没有过期但得到相同的结果 我当前的 ticketExpirationPolicy.xml 文件：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:p="http://www.springframework.org/schema/p"
   xmlns:c="http://www.springframework.org/schema/c" xmlns:util="http://www.springframework.org/schema/util"

                       http://www.springframework.org/schema/util/spring-util.xsd">

<bean id="serviceTicketExpirationPolicy" class="org.jasig.cas.ticket.support.MultiTimeUseOrTimeoutExpirationPolicy">
    <!-- This argument is the number of times that a ticket can be used before its considered expired. -->
    <constructor-arg
        index="0"
        value="1" />
    <!-- This argument is the time a ticket can exist before its considered expired.  -->
    <constructor-arg
        index="1"
        value="10000" />
</bean>
<bean id="grantingTicketExpirationPolicy" class="org.jasig.cas.ticket.support.NeverExpiresExpirationPolicy" />
</beans>

一个附带问题：我在哪里以及如何定义一个服务来充当代理？！

Answer 1

好吧，我通过将第二个构造函数参数从 10000 增加到 100000 来修复它

<!-- This argument is the time a ticket can exist before its considered expired.  -->
<constructor-arg
    index="1"
    value="100000" />
