Would make more sense if you'd simply posted the output from running

ls -l /home/pi/samba
ls -l /home/pi/samba/usermap.txt

in a console.

Where's are the log messages output by Samba daemons on the Pi? We need
to see those and not some uninformative 'Didn't work again' comment.

The best way to sweep up log messages is to run:

sudo grep -P '(samba|smbd|nmbd|winbindd)' /var/log/* | less

which display all log messages that contain the names of Samba daemons,
each line prefixed with the logfile name and starting with a timestamp.
Extract and post the relevant ones here, i.e. those written at the time
you tried to make a Samba connection.

*OR*

Open another console window on the RPi and run

sudo tail -f /var/log/messages

in it and, while that's running, try to start a Samba session on the RPi.
This assumes that Samba daemons log messages to /var/log/messages rather
than some other log - if they write to private logs their names will be
obvious if you look at a directory listing of /var/log

'tail' displays messages as they are written appended to file until you
kill it with Ctrl/C

I no longer use Samba (no need to as I no longer use Windows for
anything) but from memory looking at the messages it logged was key to
fixing problems with it.
