X509N:<S>CN=QlikClient "Kerberos Authentication Service" Event Type : Failure ; Failure Reason- Bad User name

Hi All,

We are in Qlik sense Feb 2022 version and are notified by the windows administrators about the below issue in domain controllers.

X509N:<S>CN=QlikClient "Kerberos Authentication Service" Event Type : Failure ; Failure Reason- Bad User name 

Though we don't have any issues in Qlik environment but the failed logins are causing performance issues in domain controllers.About 66000 failed logins are reported daily.

Can anyone help me with the issue.

Thanks
