Ohh, no - you don’t want to do that. Why would you do that?
NFS without kerberos uses the UIDs of the remote users to determine access to files on the server. It’s very insecure since the client systems can use whatever UIDs they want. It’s why NFS has a “squash root” option which blocks any remote system from using UID 0. Kerberos allows users to authenticate so that the server knows who they are on the local system rather than trusting the remote system.
Changing ownership to “nobody” doesn’t give anyone access - it just sets the owner to the “nobody” user. You would need to “chmod” to give read/write permissions.
