CAS ticket validation always fails - spring-security

Question

I installed CAS 4.1 successfully and configured it to use Active Directory as backend authentication. Now the problem is, that each time I try to validate a ticket CAS server complains about the ticket has expired. The steps i've been doing to get and validate a ticket are as follow:
call https://sso.domain.net/cas/login?service=https://myservice.domain.net
I get a ticket such ST-2-NLOngMHayTl3uCLKn91T-sso.domain.net
Call validation service https://sso.domain.net/serviceValidate?ticket=ST-3-zrjAFf1UU95NdzGmCibv-sso.domain.net&service=https://myservice.domain.net
And I get the following response:
<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>
Ticket granting log shows

I used the same ticketExpirationPolicy.xml from this StackOverflow entry
and I got the same result, I tried also changing to no expiration at all but get the same result
My current ticketExpirationPolicy.xml file:
<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"

xsi:schemaLocation="http://www.springframework.org/schema/beans

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

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>
A side question: where and how do I define a service to act as a proxy?!

Answer 1

Well, I fixed it by increasing the second constructor argument from 10000 to 100000
<!-- This argument is the time a ticket can exist before its considered expired. -->
<constructor-arg
index="1"
value="100000" />
