@dbabbitt : that is something different, that is the docker driver (not hyper-v) and seems to be a duplicate of #8100

Thanks for the redirect!

Based on the command-line:

minikube.exe --extra-config=apiserver.Authentication.PasswordFile.BasicAuthFile=C:\Personal\Kubernetes\users.csv start --driver=hyperv

The YAML issue is because the backslashes being passed in not being valid (and not being escaped on our end). The path given needs to exist within the VM, not on the host. I suggest using https://minikube.sigs.k8s.io/docs/handbook/filesync/

• Add the file to C:\Personal.minikube\files\etc
• Specify BasicAuthFile=/etc/users.csv

Hi @, I haven't heard back from you, I wonder if you still have this issue?
Regrettably, there isn't enough information in this issue to make it actionable, and a long enough duration has passed, so this issue is likely difficult to replicate.

I will close this issue for now but please feel free to reopen whenever you feel ready to provide more information.
