I am wondering if anyone has kerberized nfs4 working with 12.0-U5+ or if this is some issue with my setup? Or is this feature not commonly used "in the wild"?
I too wonder this. I gotta say that kerberized nfs4 has been a pain for me since I first stuck my toe in the water years ago. When I have had it working, it always feels held together with ducttape and I daren't look at it too hard lest it falls apart.
I keep trying to convince myself that it's just my unfamiliarity or wonky homelab setup, and that the sysadmin greybeards just have the dark arts of making it work locked up in their heads as tribal knowledge, but I increasingly wonder it's just an awkward set of tools to work with. I keep meaning to try out a similar setup with pure linux-linux kerberized nfs4 to see if it's easier (and since I have more experience with linux than bsd) although even then it doesn't exactly feel like the mainstream either.
On the other hand, if people aren't using kerberized nfs4 then what are they using? nfs <4 or with sec=sys seem easier/more reliable but lack integrity or encryption which seems a bit limited in the new world of zero-trust security, especially when the encryption performance overhead is relatively minor. Samba seems popular, and I have too little experience with it to say with any certainty, but from the little I've used it, it never really feels Linux native, especially when trying to get centralized auth and identity setup. sshfs also seems popular, and while I see the appeal for quick and easy access to remote files, it doesn't seem like a practical replacement for NFS. Searching for alternatives, everything else either seems aimed at a much larger scale (glustefs and the like) or too obscure (webdav I guess is an example).
I think this will be my last attempt to get it working solidly again on TrueNAS. If it doesn't slay the beast, I think I'll try if I can get smb working nicely, or I guess maybe if linux-linux nfs4 is less painful that might be an option. Although how that will help me with TrueNAS...I don't know if TrueNAS Scale is any less painful being Linux based.
