Eu resolvi isso com essa configuração:
[global]
# allow hosts = 127.0.0.1 192.168.1.0/24
workgroup = debianizzati
server string = [email protected]
security = user
guest account = ospite
map to guest = Bad User
#username map = /etc/samba/utenti.map
netbios name = debianizzati
#netbios aliases = alias1 ... aliasN
#include = /etc/samba/smb.conf.%L
#passwd program = /bin/passwd %u
#pam password change = yes
#obey pam restrictions = yes
#passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuc$
#unix password sync = Yes
[condivisione]
path = /home/utente1
valid users = utente1
read only = no
guest ok = no
[condivisione 2]
path = /home/share
guest ok = yes
read only = no
