Event 4771: Kerberos pre-authentication failed

Hi MS Community,

I am facing this persistent issue whereby my domain account keeps getting locked out due to Kerberos preauthentication failure. This issue surfaced only after we started using a Privileged Access Management (PAM) software to remote in to our target servers.

Any tips on how to resolve this lockout issue?

Thanks!
