Started the systemctl restart nfs-idmap.service. If I go back to NFSv3 it all looks OK. It also seems to be only a problem with Fedora 17 at the moment. I did a clean install with Fedora 16 and had it working properly then did the upgrade to 17 and NFSv4 is missing some, not all, of the mappings. That list above is a small paste of about 300 users. I then did a clean install of Fedora 17 and it also has the same problem. About 20% did the UID/GID mapping and showed the username while the rest showed the nfsnobody mapping. Re-mounting to NFSv3 fixes the listing. I wonder what email client you are usingsince it quotes previous poorly making it hard to determine who wrote what. Your NFS4 server systemwhat is that? You said you're only having trouble with F17 as the NFS4 client. You've also said that some uid/gid are mapping correctly while others are not. Would it be possible to give a larger sample size than the 2? And could you do an ls -ln with the file system unmounted just to verify the mount points were created correctly? I only have a few exported file systems and a few users and not seeing any problems. Maybe you can describe your exports and mount points a bit more?

I was just curious that maybe specifying the sec options and other may be confusing the system.

But I just wrote a bugzilla against it for random mounts failing at boot time. Since I don't see mapping problems I'd be more suspect of NIS.
