One particular unusual environment I have observed is such that on a NFS
client, files are reported as having owner/group being nobody/nobody,
but actual access to files is correctly handled by the NFS server using
UIDs/GIDs. Correctly meaning that the effective UID/GID of the process
executing on NFS client is handled by the NFS server when granting
particular operations on files/directories as they appear on NFS server.
These are the mount options reported on NFS client, which is Linux
server:/directory on /directory_nfs type nfs
The NFS server is a Solaris box (Solaris 10, sparc) which speaks NFSv4
and runs the nfsmapid daemon, but the client is not running the idmapd.
Hope this helps.
