Network and Storage Protocols
I have a test lab with ONTAP simulator at 9.13.1 version, and Microsoft published windows server 2025 last month, so I want test ONTAP with new OS.
1.Windows server 2025 is installed and active directory service is installed.
2. During the cifs create procedure, it shows an error: Machine account creation procedure failed.
3. From wireshark capture, it shows kpasswd replyed an error.
The user account in this kb used to add a computer account is using an incorrect password
Machine Account Creation Procedure Failed - KRB5KDC_ERR_PREAUTH_FAILED - NetApp Knowledge Base
Or the user credentials are incorrect Machine account creation procedure failed with KRB5_REALM_UNKNOWN error - NetApp Knowledge Base
If you check Interoperability Matrix for CIFS, Windows 2025 Server is not yet listed, so the validation is not executed yet.
The error is pointing to a duplicate/reused account on Domain Controller for the SVM.
Please retry posting the full secd log for cifs create call to understand the reason for the failure
thanks your reply, I don't know how to collect full secd log, bellow is what I collected logs.

It seems there is a problem on Microsoft side for kpasswd (Kerberos password change service) and it is investigated by Microsoft at the moment.
Any updates to this problem? The suggested work arounds selecting a different preffered DC only works for already domain joined SVM´s.
Unfortunately we have to wait for Microsoft to provide a fix
Preferred DC and discovery modes can be set even before cifs server creation (like the security settings)
There are people reporting that in WS2025 September update this kpasswd bug might be resolved (see https://gitlab.freedesktop.org/realmd/adcli/-/issues/40).
Could that mean that this problem (also described in https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-Issues/CONTAP-347583) has been finally resolved?
