Solution Verified - Updated -


  • NFS Client fails to mount NFS share with krb5p option with error below:
# mount -v -t nfs -o rw,vers=4.2,sec=krb5p <NFS share> <mount point>
mount.nfs: timeout set for Wed Jun 15 07:11:37 2022
mount.nfs: trying text-based options 'vers=4.2,sec=krb5p,addr=<NFS Server IP>,clientaddr=<NFS Client IP>'
mount.nfs: mount(2): Permission denied

  • NFS Client can successfully mount the same NFS share without krb5p option.
  • /var/log/messages is getting the log entry below per second:
