Feature Request - NAS Filer Backup with NTLMv2 disabled

[ungruha]

After creating a ticket (07713942) I was asked to create a forum post marked as feature request (I hope I´m doing this the right way).

So my problem is, that we need to turn off NTLMv2 for security reasons. So our proxy servers are no longer able to use ntlm(v1/v2) and use kerberos properly.
However, when performing a backup of a NAS Filer (NetApp) I am not able to perform that specific task.

Environment:
- Veeam B&R 12.3.2.3617 (running on Windows Server 2022)
- NAS Proxy Server (running on Windows Server 2025)
- NetApp AFF as NAS Filer running in Metrocluster Configuration
-- Cluster is added as NDMP Server for Tape Backup purposes
-- Cluster is added in Storage Infrastructure for VMware vSphere Backup purposes
-- Cluster is added as NAS Filer (adding specific NAS Filer storage vm is not allowed)

Expected behaviour:
- NAS Filer backup via storage snapshot is possible via kerberos authentication

Actual behaviour:
- Backup fails to authenticate with error message "<date and timestamp> :: Error: Agent: Failed to process method {NasMaster.CreateBackupProcessor}: Authentication failed because NTLM authentication has been disabled."

Probable cause:
- Veeam tries to contact the cluster instead of the storage vm and therefore the authentication fails. Adding the storage vm in NAS Filer section should solve this problem, but fails due to certificate errors ("You cannot have both the cDOT cluster and its SVMs registered with Veeam Backup and Replication at the same time.").
