First questions (sorry if it's obvious):
- Do you have a valid token on the client? (obtained with kinit)
- Did you import the keytab for NFS service on the server?
- Did you put "domain = yourdomain.tld" in your NFS server config file? On
- Depending on your (ipa? nfs?) version you may have to enable weak crypto
(I saw this everywhere but never had to do it for a reason I still ignore)
I'm far from being the most informed people on this list, but I think it
may be the first things to check.
Hope this helps,
