Symptoms

Some users are seeing the following error when they open a SmartForms integrated work item, or simply opening the Worklist web part that is hosted in SharePoint online. (Other users are unaffected.)

Error: Exception of type 'System.Web.HttpUnhandledException' was thrown.
ID4148: The Saml2SecurityToken is rejected because the SAML2:Assertion's NotOnOrAfter condition is not satisfied. NotOnOrAfter: EarlierDateAndTime] Current time LaterDateAndTime]
 

Diagnoses

This was an issue on "older builds". In this case, it was on 4.6.9 and we have done a lot of work surrounding this area in 4.6.11 and especially on 4.7.
 

Resolution

After the upgrade to 4.7, the issue has not been reported again. We will monitor the situation and if this happens again, we can log a new ticket and continue working the issue there.
