We have an evaluation system setup that we are using to generate PDF from PS. We're connecting via the EJB client, and typically have had no problems. Until today. At some point today we began seeing exceptions being thrown on the client:
Caused by: com.adobe.idp.um.api.UMException | [com.adobe.idp.um.api.impl.AuthenticationManagerImpl] errorCode:16421 errorCodeHEX:0x4025 message:Could not validate SAML Token --- Assertion has expired and hence not valid for user [administrator@DefaultDom]. Its valid till time [Tue Feb 04 10:58:45 MST 2014] was found to be before the current time [Tue Feb 04 16:04:41 MST 2014]
Simply bouncing the app server where the client code is running solved the problem, however we'd like to better understand what is going on and why. Nothing that I can find in the docs seems to indicate the cause/solution, and possible solutions have links that appear to no longer function: http://cookbooks.adobe.com/post_Renewing_the_context_to_handle_session_expiry-16410.html
Any suggestions and/or insight would be greatly appreciated. Thanks!
