Creating files on an NFSv4 share results in incorrect ownership when UID/GID's do not match on Red Hat Enterprise Linux

Solution Verified - Updated -

Issue

  • Changing ownership of a file from the NFS client functions as expected and the proper user and group is visible via an ls -l or stat issued from the client.
  • Creating files as a user on the NFS client results in the files' ownership being modified to the nobody user when the file ownership is inspected from the NFS client and as the numeric uid/gid when inspected from the NFS server:
NFS server:
# ls -l
 -rw-r--r--. 1  1003 wheel          0 May 16 15:20 testfile

NFS client:
# ls -l
 -rw-r--r--. 1  nfsnobody  wheel     0 May 16 15:20 testfile

Environment

  • Red Hat Enterprise Linux 5 or above
  • Client mounting NFSv4 share
    • uid/gid's differ between NFS server and NFS client
