Looks good.

Please show us the content of /etc/nsswitch.conf.

OK. So in your smb.conf file add the following to the [global] stanza:
	log level = 5
	log file = /var/log/samba/%L-%m.log
	max log size = 0

Then try to connect using smbclient. This will generate a log file that
is rather detailed.  Check to see the reason it is failing.
