The user guest exists, I've tried to set the password to none (-n option of 
smbpasswd) and now I can enter the samba server also without specifying a 
user (if I specify a non-existent username, as you suggested, I can enter the 
share).

Thanks a lot for your suggestions.
I've got only another doubt: being public the share, is there a possibility to 
block access to a few users or machines in an ip list? Can I work with such 
parameters in a guest ok share?


Thanks,
Luca
