In web.xml, you can adjust ticket timeouts. Specifically, the ticket granting ticket timeout is specified as the context parameter "edu.yale.its.tp.cas.grantingTimeout". It is specifed in seconds, and its default value is two hours.

<!-- Timeout for granting tickets -->
<context-param>
<param-name>edu.yale.its.tp.cas.grantingTimeout</param-name>
<param-value>7200</param-value>
</context-param>
|
Since the timeouts are stored as integers (max value 2,147,483,647) and converted to milliseconds, the maximum timeout in seconds is: 2147483 (almost 25 days). If you need longer timeouts than that, you will have to change 'int' to 'long' for timeouts and tolerances in the CAS java code.
