[Samba] Only one user for a file

Well, just to add my 2 cents, locking=no is an insane thing to do.  By all
means, you can use it to test and satisfy your curiosity, but be aware
that data will become corrupt very fast.

I'm not sure what you mean wit "restrict the use to one user". Do you
mean if one user runs the application and an other one wants to start
it simultaniously, he gets a permission denied? In this case I would
try "locking = no" and a few other parameters for the share in
smb.conf. Or do you mean only a certain user can run the application
independend from what the other do? Than you may have to tune file
and directory permissions. Does this application need to write to its
files (ini's, locking, ...)

With Unix users and groups you can be very tricky, and if you do not
maind to set up a couple of groups everything commonly needed can be
done. Or, a last in my experience: It can be done more than the
normal user wants to use actively (to my option file permissions of
data is user stuff not admin work). If you realy run out of
possiblities you can set up ACL'a on Unix to.
