Active Directory Kerberos

Active Directory team will be resetting the password of the Active Directory Key Distribution Center (KDC) service account (KRBTGT) across the Active Directory domains.The recommendation calls for resetting of the KDC KRBTGT account passwords every 180 days. The KDC service account caches its 2 most recent passwords. Hence the need to reset the password twice replace the current cached passwords as recommended, scheduled for May 25 and June 8.

Hoe can we verify that our CPQ application using Active Directory Kerberos authentication, will not be impacted by the KDC password resets?
