Dans la section "global" de mon smb.conf, j'ai ça, et j'ai pas de problème de mot de passe.
[global]
# workgroup = NT-Domain-Name or Workgroup-Name, eg: LINUX2
workgroup = REZO
null passwords = yes
guest account = nobody
map to guest = Bad User
# server string is the equivalent of the NT Description field
server string = Samba Slackware Server
# this tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba.%m
# Put a capping on the size of the log files (in Kb).
max log size = 50
# Security mode. Most people will want user level security. See
# security_level.txt for details. NOTE: To get the behaviour of
# Samba-1.9.18, you'll need to use "security = share".
security = share
socket options = TCP_NODELAY
wins support = no
Voilà un répertoire en accès complet sans mot de passe :
[RW_Samba]
path = /home/samba
public = yes
guest only = yes
comment = Lecture Ecriture 1Go dispo
writable = yes
Et un répertoire en lecture seule sans mot de passe :
[partage]
writable = no
guest only = yes
comment = Truc partage
path = /home/jak/samba
public = yes
Tout ça pour un Samba version 2.2.0a
