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://10.1.1.26:8080/login, the validate url is http://10.1.1.26:8080/serviceValidate.

Then I tested it like below:

1. call http://10.1.1.26:8080/login?service=http://10.1.1.9:8081/default.aspx
2. I get the service ticket successfully, such as ST-9-pJ5UDxqKIHP2zuN3JGe4-cas
3. then I validate the service ticket by calling http://10.1.1.26:8080/serviceValidate?ticket=ST-9-pJ5UDxqKIHP2zuN3JGe4-cas&service=http://10.1.1.9:8081/default.aspx,
4. unfortunately, it always return invalid ticket,

in order to fix it, I try cas 1.0 validate url, http://10.1.1.26:8080/validate?ticket=ST-9-pJ5UDxqKIHP2zuN3JGe4-cas&service=http://10.1.1.9:8081/default.aspx, but it return "no".

Then I generate a certificate file and put it into keystore, then I tried all the above steps by using https://10.1.1.26:8443, howevery, the validation was still failed.

I changed the cas log4j configuration, to print all debug information, and below is the log

What I don't understand and don't know why is from other post I saw log has something like " write service ticket to ticket registry, and retrieve service ticket ", but there is nothing about that in my log

Solution

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

Same problems as here, apparently the default expiration time is very short. I changed and it worked.
