i may be naive a bit, i'll accept that, but I really like how AD works (which is essentially kerberos + ldap)
Ultimately I gave up and used samba instead, but it does seem like there's a big gap in linux offerings for "home/small business network file sharing" with shared auth
I also want to share the home printer/scanner, which I believe samba can do, but obviously sshfs won't. Side note - I would love to see a standard protocol and server for a 3d printer. We have a Bambu and the software is... alright... but doesn't play nice sharing an account between computers.
Ultimately I set up samba on the server, with mapped users, and a line in fstab on the desktop. Plain old NFS might have worked for the desktop but the users don't have the same UIDs between the desktop and the server and... reconciling that seemed painful.
I did try to make kerberos work with NFS for a few days but the experience was akin to staring into the sun.
