I have a Synology NAS which, among other things, hosts a shared drive. It’s exposed via SMB & NFS. When I mount the share as NFS on my linux machine, the user IDs don’t match and permissions are all messed up.

On my old NAS, I had it set up first so when I added users to the linux machine, I picked the user IDs so they’d match, but the Synology has a different starting ID and I don’t want to renumber my users on the client.

I’m trying to keep it simple, so I’d rather not delve into the rabbit hole of LDAP, AD or Kerberos. I was debating just mounting CIFS or SMB with a generic user, but that doesn’t feel right.

Has anybody done much with user mapping in NFS4? How well does it work? Is there a simple solution? I was hoping for a drop in replacement without a lot of time lost. What do you do on your system?

Specs: 4 users, 4 laptops, 1 Apple, 2 windows, 1 linux, 2 linux servers, 1 Synology NAS. 1 overworked admin.
