I've setup NFS4 on my network of Ubuntu computers (one server to which several clients mount) according to this link
. I can successfully mount the NFS exports and access them when I have acquired a valid Kerberos ticket.
However, every file/directory on the exports appear as being owned by nobody:nogroup to the clients.
Yes, I have set "NEED_IDMAPD=yes" in /etc/default/nfs-common on the server and clients.
Yes, I have verified that rpc.idmapd is indeed running on the server and clients.
Yes, I have set "Domain = [mydomain]" to the same domain in /etc/idmapd.conf on the server and all clients.
I actually did remember getting the names to map correctly once immediately after I changed the "Domain =" line, but I don't know if I rebooted or what and it now no longer works.
