In November 9 2021, Microsoft release a monthly security update, which imporves authentication safaty described in CVE-2021-42287
I have a test in NAS lab:
1. Windows server 2019( with KB5007206): Set PacRequestorEnforcement registry value to “2” (Enforcement phase)
2. Ontap simulater 9.8P7: A SVM join AD domain with administator
It returns "join failed".
Trace packet shows an error about KPASSWD, seems that initiate the password of machine account
See The Solution
Closing the loop... this issue is tracked by Bug 1465232 - CIFS password change operation might fail.
There are ONTAP fixes in various branches, as well as a workaround if an ONTAP upgrade is not possible at this time.
