Problem: When the restore is started with \server.domain.intra\BackupShare$, the restore finish successfully but with the DNS alias we get the error "Operating system error 1326(The user name or password is incorrect.)"
I have the feeling that the gMSA should be configured to allow to be delegated to the dns alias. Or do you have any other ideas how to solve the problem?
Thank you very much and kind regards, Olaf
To allow Kerberos Authentication on the network share, you need to add the SPN for the alias with the
HOST service (it's actually a group of services), as otherwise the server is not able to create a Kerberos ticket for it.
The server itself does not realize that it is connecting to a loopback, so even if it's on the same server it needs the SPN.
setspn server.domain.intra -s HOST/server-db-dev.domain.intra
