Hi Vishal,
From the screenshot above, it is not clear to me what exact error is administrated in /IWFND/ERROR_LOG, when you invoke the RoleSyncService from SharePoint control. Is it about the missing role-entries, or the invalid timestamp format?
Did you check How to Configure and Execute Role Synchronization in Duet Enterprise 2.0?
Update: I noticed that Microsoft Edge fails to open the PDF. Use any of the other browsers (IE, Firefox, Chrome, Safari) instead.
William.
