Olá Pessoal,
há uma semana que venho tentando resolver um problema que parece ser simples, mas pelo jeito, não achei solução ainda.

Preciso configurar o samba para que ao abrir a rede pelo windows (xp, vista, win7) me mostre o servidor samba na rede com as seguintes pastas: Publica e privada.

a publica, devo entrar sem problema algum, mas a privada deve exigir um login e senha.

só isso, parece ser simples, mas nao consegui ainda.

Já peguei varios exemplos aqui, onde quando clico no servidor, me pede senha, consigo até logar, mas abro todas as pastas, outras me pede senha na primeira pasta onde logo, mas na segunda pasta quando digito a senha diz que nao é possivel varios usuarios acessar simultaneamente.
se alguém tiver uma solução simples pra isso?
já utilizei o share e o user.
Este smb.conf que posto aqui é o ultimo que estou tentando, qualquer dica será bem vinda.
Mas acho interessante que o samba há tanto tempo existindo não encontrei nada sobre isso, ou pelo menos não com a solução.

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#======================= Global Settings =====================================
[global]

#printer = hp-laserjet-1200-2
# workgroup = NT-Domain-Name or Workgroup-Name
workgroup = teste

# server string is the equivalent of the NT Description field
server string = Servidor Linux

# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
; hosts allow = 192.168.1. 192.168.2. 127.

# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this

# It should not be necessary to spell out the print system type unless
# yours is non-standard. Currently supported print systems include:
# bsd, sysv, plp, lprng, aix, hpux, qnx
; printing = cups

# This option tells cups that the data has already been rasterized

# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.

; wins server = w.x.y.z

# behalf of a non WINS capable client, for this to work there must be
# at least one WINS Server on the network. The default is NO.

Olá, as permissões estão funcionando para a sua pasta principal, mas não está funcionando para as suas subpastas? é isso? se for isso vc precisa dar um chmod -R ex:
Chmod –R 770 /usr/suporte ( -R recursiva a permissão se da para as pastas e subpastas).

O parâmetro

encrypt passwords

está duplicado

Remova o que tem o valor no e deixe o que tem o valor yes


4. continua pedindo senha

Alterei a opção, mas continua pedino senha.
Como deveria ficar as permissoes de pasta e para qual grupo deveria ficar setadas?
tem alguma coisa a ver?

Verifique as opções do samba, pois se você colocar para security = share não deve pedir senha.

Peço que posta seu smb.conf para análise

Márcio, vamos começar por um arquivo que funciona o acesso à pasta público sem senha. Você disse que encontrou um que funciona, então posta ele aqui e vamos trabalhar em cima dele. Depois que conseguirmos acessar sem senha vamos pro próximo nível que será acessar a pasta suporte com senha.

Senhores,
Esse smb.conf está como security = user e compartilha uma pasta publica que não requer login e senha, agora precisamos descobrir como compartilhar uma segunda pasta que somente usuarios registrados possam através de login e senha entrar na mesma.

[global]
#unix password sync = no
workgroup = workgroup
printing = cups
printcap name = cups
printcap cache time = 750
cups options = raw
map to guest = Bad User
include = /etc/samba/dhcp.conf
logon path = \\%L\profiles\.msprofile
logon home = \\%L\%U\.9xprofile
logon drive = P:
usershare allow guests = No
add machine script = /usr/sbin/useradd -c Machine -d /var/lib/nobody -s /bin/false %m$
domain logons = Yes
domain master = Yes
netbios name = LINUX
passdb backend = smbpasswd
security = user
wins support = Yes
log file = /var/log/samba/log.%m
log level = 2
max log size = 500
load printers = No
server string = Controlador de Dominio
local master = Yes
os level = 65
preferred master = Yes
unix charset = iso8859-1
display charset = cp850
logon script = %U.bat
share modes = Yes
usershare max shares = 100
time server = Yes
timeserver = Yes
ldap suffix =
[publico]
comment = Acesso Publico
inherit acls = Yes
path = /home/samba
read only = No
create mask = 1754

Primeiramente acrescente, na seção global, e abaixo de passdb backend = smbpasswd, a opção

smb passwd file = /etc/samba/smbpasswd

Depois disso rode o comando abaixo para criar o arquivo de usuário e senhas do samba no local indicado

cat /etc/passwd | mksmbpasswd > /etc/samba/smbpasswd

verifique o conteúdo do arquivo

cat /etc/samba/smbpasswd (não precisa postar)

reinicie o servidor samba, a exemplo do debian

/etc/init.d/samba restart

adicione um novo usuário do sistema no samba

smbpasswd -a usuário

digite e confirme a senha do usuário para o samba

verifique se o novo usuário foi incluso no arquivo /etc/samba/smbpasswd

cat /etc/samba/smbpasswd

Crie a pasta a ser compartilhada no sistema (caso já não exista)

mkdir /home/suporte

defina o dono, grupo e as permissões do usuário (substitua dono e grupo pelos verdadeiros)

chown dono.grupo /home/suporte

chmod 6770 /home/suporte

Adicione o compartilhamento no samba

[suporte]
path = /home/suporte
comment = Documentos do suporte
null passwords = no
browseable = yes
writeable = yes
force directory mode = 6770
directory mode = 6770
create mode = 6770
public = no
valid users = usuário, @grupo

reinicie o serviço do samba e teste o compartilhamento na rede.

quando eu mudo meu security para share ele entra normal sem senha na publica, e pede senha para a pasta suporte, porem ele deixa o usuario fixado como convidado(servidor\convidado) nao permitindo a troca deste usuario...

muda a opção usershare allow guests para yes e adiciona a opção public = yes no compartilhamento publico.

reinicie o serviço e testa

Primeiramente quero pedir desculpas pela informação incorreta de que usando security = share ele acessaria sem senha.
O que o security = share faz é usar uma senha para cada recurso compartilhado e não por usuário. Isso quer dizer que cada compartilhamento poderá ter uma senha única, em vez de com uma única senha você acessar mais de um compartilhamento.

Então vamos a uma próxima tentativa.

Na seção global deixe a security = user mesmo e adicione ou modifique os parâmetros a seguir

guest account = nobody
guest ok = yes

A partir disso, basta usar guest ok = yes no compartilhamento público e guest ok = no no compartilhamento privado.

Obs.: guest ok é sinônimo de public, então utilize somente um dos dois.
