018-728 Kerberos Attestation Protocol Error 72 RAP

018-728 The Kerbeors server KDC certificate is incorrect (the root CA certificate is not registered with the machine; the KDC certificate has expired; or the KDC certificate address is different from that written on the certificate.)


Advise the customer to:

1. Check if the root CA certificate of KDC certificate is registered with the machine. If not, register the root CA certificate.
2. If the KDC certificate has expired, renew the Kerbeors server KDC certificate
3. Check that the Kerberos server address set on the machine is the same as that written on the Kerbeors server KDC certificate. If they are different, change the Kerbeors server address set on the machine, or check the Kerbeors server KDC certificate. In this case, there is a possibility of a wrong setting or Kerbeors server impersonation.
