  How do i identify if kerberos is being used?

  I have read online that i can check for some events on the security logs on the Domain Controller, but is there anything i can do on:

  1. My client machine that connects to sql server on a different server.

  2. From the sql server machine.

  Thanks!

  Hi,

  You can check kerberos is being used or not by running below query

  USE MASTER

  GO

  SELECT AUTH_SCHEME FROM SYS.DM_EXEC_SESSIONS

  If output will be kerberos ,log on process is by kerberos authentication.

  or by

  Start->Run->gpedit.msc->Computer Configuration, Windows Settings, Security Settings, Local Policies, Audit Policy, "Audit logon events".

  Check the "Success" and "Failure" check boxes. Try logging out and logging in to see some typical 540 events in your Windows Security Event Log.

  From the event log information,we can able to find the logon process by kerberos or not.
