CAS service ticket validate failed

Question

I have followed a link http://lukesampson.com/post/315838839/cas-on-windows-localhost-setup-in-5-mins, then the cas server works correctly, the login url is http://10.1.1.2

I'm not 100% sure because I can't see your configuration, but the log says this

<ServiceTicket [ST-1-pqIeCRqcafGBE6idoCcd-cas] has expired.>

Which means that the ticket has already expired. There exists a config-file in CAS called ticketExpirationPolicies.xml which contains the times a ticket is valid. In my CAS-version the expiration period for a service ticket is set to 10000ms. Maybe the time between you step 1 and 3 is longer than the expiration setting in your file (of course) which could differ from mine

<!-- Expiration policies -->
<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.TimeoutExpirationPolicy">
    <!-- This argument is the time a ticket can exist before its considered expired.  -->
    <constructor-arg
        index="0"
        value="7200000" />
</bean>

The tutorial that you follow in my opinion is not complete in its configuration settings. Depending on what you try to achieve with this CAS-server you could need some of the customization described here
