Mapping UID and GID of local user to the mounted NFS share

First of all, enable is on the client and server:

echo N > /sys/module/nfsd/parameters/nfs4_disable_idmapping

nfsidmap -c

service rpcidmapd restart

My need restart NFS server and/or client…

/etc/init.d/nfs-kernel-server restart

Now on server and the client will send instead of numeric IDs string principals like bob@YOURDOMAIN.COM. You need to have bob account on the both hosts - client and server.

Nevertheless, the numeric ID’s can be different.
