This configuration mechanism is valid for IdP versions prior to 3.4.

PKIX-based CAS proxy trust is configured in relying-party.xml as part of the profile configuration for a particular relying party. The following configuration excerpt demonstrates configuring CAS to accept proxy callback certificates issued by a handful of trusted issuers for the default relying party.

Service Ticket Expiration (Optional)

CAS Service tickets issued by the Shibboleth IdP are single use tickets with a default validity period of 15 seconds. It is possible to extend the validity period by altering the profile configuration in relying-party.xml as follows:

    <!-- Default configuration, with default settings applied for all profiles. -->
    <bean id="shibboleth.DefaultRelyingParty" parent="RelyingParty">
        <property name="profileConfigurations">
            <list>
                <ref bean="Shibboleth.SSO.default" />
                <!-- ... other SAML profiles ... -->
                <bean parent="CAS.LoginConfiguration" p:ticketValidityPeriod="PT5M" />
                <ref bean="CAS.ProxyConfiguration" />
                <ref bean="CAS.ValidateConfiguration.default" />
            </list>
        </property>
    </bean>
