NFS with Kerberos password authentication?

[dusf]

I Samba working with password authentication and I am happy streaming from it to my H Series Samsung TV so far. For tasks on other devices I would prefer if it were faster. As NFS is faster I would like to try using it and I found this in the Wiki:

Mounting an NFS share on a USB device to bypass DLNA

I am assuming that is the most up to date guide I should be following.

NFSv4 supports authentication using Kerberos, this would offer faster speeds file sharing and also authentication for security, the only issue I can see is that the guide I linked above does not mention authentication, Kerberos, or usernames and passwords etc.

Is there anyway to make NFSv4 and authentication work with a Samsung TV?
