[Samba] linux users account authentication

[Meli Marco]

Hi, I have set smb.conf as following, but I can't log with smbclient on the
data share with a local linux user, saved in '/etc/passwd' and passwdsmb,
while with others domain users works fine.
I have also set nsswitch.conf: file to files winbind ... and PAM modules
also is configured.
Whats wrong?
Thanks a lot.
