Trying to configure NFSv4 and Kerberos - have managed it several times now with boxes that are on the domain, but for various reasons, this one doesn't have a CIFS license.

I'm getting an error:

"unable to setup kerberos for NFS could not set up active directory KDC"

After entering my administrator account in "nfs setup".

Can anyone point me in the direction of what I'm missing here? (Am wondering if it's some variant of needing a machine account created to act as a service principal, or something else is going wrong).
