We've had just this problem, and our solution was to use:
force create mode = 666
in the share definition where you keep your database. This means that when
Access creates a lock file (.ldb), which it does as a specific user, it
creates it with mode 0666 which means that any other user can modify it,
which is what you need for multiple concurrent use of an Access database.
The first user creates the lock file if it doesn't exist, and all
subsequent users modify it to announce their presence.
Sure, there are permissions issues with this. Perhaps there's a way of
special-casing .ldb files.
I suppose that this is the default for a Windows server (hence no problems
with sharing Access databases), so maybe this point should be made more
clearly in the Samba documentation - perhaps even pointed out in the
