If all the users in all the machines accessing the share in your network
share the the same UID namespace without conflicts, then in that case
you could use idsfromsid I think. With it, any *new* file created by
user bob will show up on the share as owned by a special SID that
contains the UID. And only files created with that mount options should
be listed back with bob uid.
That being said, if you have the same uid namespace on all machines for
user bob, that means you already have some sort of centralized
identication server similar to AD and are using winbind or sssd.
I realize you might not want to setup AD in your small network, but by
default all users uid start from 1000. So if you have machineA where you
created user bob (1000) and bart (1001) and machineB where you created
user james (1000) and judy (1001) and try to mount with the idsfromsid,
then files created by james on machineA will show up as owned by bob on
I hope that clears up some confusion.
