(sorry in advance for the long post)
What I’m looking for:
Basically, without a lot of work to setup and maintain a Domain/Kerberos server, what’s the best way to provide consistent logins and remote folder/share (from a server) access across various Linux desktops
I’ve configured domain controllers using Samba. I’ve also configured Linux systems as domain-joined hosts. Between the two I tend to find that keeping talking - especially for systems that are only on infrequently - can be a bit troublesome. Updates sometimes break the Samba server, tokens expire, etc etc
I’ve also used NFS of various versions, but found v4 with the Kerberos implementation a bit finicky (for similar reasons to the SMB based implementation). NFSv3 of course is fairly fast and efficient, but lacks the user-level authentication and relies on IP’s for access-control.
Now it’s been awhile since I’ve given a shot at this except for some NFS shares between VMs and SSHFS for desktops, it would be nice to have a consistent but easily maintainable way to provided common shares for larger files (videos, albums, 3d models, and projects etc) without having to constantly troubleshoot. Maybe the domain/NFS route had gotten easier but it still seems to be fairly manual at times.
I use SSHFS. I have had some trouble getting it to mount automatically, but it will show up in Dolphin so it mounts when you click. If you set up keys (ideally ed25519), disable password authentication, set up fail2ban, and use nonstandard ports for outside lan I would consider it reasonably secure.
