This article provides details on how to enable debug logging to troubleshoot Kerberos authentication related issues in TIBCO Data Virtualization(TDV). 

To enable Kerberos debug logging :
Launch TDV Studio and Navigate to Administration tab > Configuration panel >Server >Configuration >Security >Authentication >Kerberos  and  Set this to true.

Screenshot for reference:


This will log Debug entries in the cs_server.out or cs_monitor.out file. The Kerberos debug trace will be written to one of these logs.
