macOS server - user management
have a few macs - iMac, MBP, MBA, mini.
two main users in our home. i mainly use MBP, another user travel with MBA. occasionally both of us will use iMac. mini is TimeMachine and file server. our scenario is that when we're at home, prefer to use iMac due to bigger screen. but hate transferring files to/from server, or save to server from iMac then copy to laptops and vice versa.
considering macOS server on the mini. is it possible to setup the server (and user accounts), with user directory simultaneously on server as well as local drive?
just looking for seamless operation/experience - work as normal when traveling on laptop, login locally and files stores locally on laptops without connection to mini server at home. when got back home, login automatically taken over by mini server, and files on laptops transferred to server. if decide to use iMac, login normally and expect to see exactly the same thing on desktop / user folders as the laptops.
possible? if not, may also consider to constantly dial-in to mini server via VPN, but not ideal solution.
