Samba + LDAP

Posts recomendados

Bom dia pessoal.

Já possuo diversos servidores Samba, na minha rede, buscando os usuários no diretório LDAP. Estou configurando mais um servidor Samba porém estou tendo dificuldades para fazer com que ele busque os meus usuários no LDAP. Instalei um servidor CentOS 5 com Samba 3.0.23c-2.

A seguinte mensagem está aparecendo nos logs do Samba.

[2008/01/03 09:21:48, 1] passdb/pdb_interface.c:pdb_default_uid_to_rid(1227)

Could not peek rid out of sid S-1-5-21-3952862178-2054358353-2195293624-500

Segue abaixo o meu smb.conf.

# 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

#

# For a step to step guide on installing, configuring and using samba,

# read the Samba-HOWTO-Collection. This may be obtained from:

# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf

#

# Many working examples of smb.conf files can be found in the

# Samba-Guide which is generated daily and can be downloaded from:

# http://www.samba.org/samba/docs/Samba-Guide.pdf

#

# 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]

# workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH

workgroup = samba

# server string is the equivalent of the NT Description field

server string = Samba Server

# Security mode. Defines in which mode Samba will operate. Possible

# values are share, user, server, domain and ads. Most people will want

# user level security. See the Samba-HOWTO-Collection for details.

security = user

# 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. 127.

# If you want to automatically load your printer list rather

# than setting them up individually then you'll need this

load printers = yes

# you may wish to override the location of the printcap file

; printcap name = /etc/printcap

# on SystemV system setting printcap name to lpstat should allow

# you to automatically obtain a printer list from the SystemV spool

# system

; printcap name = lpstat

# It should not be necessary to specify the print system type unless

# it is non-standard. Currently supported print systems include:

# bsd, cups, sysv, plp, lprng, aix, hpux, qnx

; printing = cups

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

cups options = raw

# Uncomment this if you want a guest account, you must add this to /etc/passwd

# otherwise the user "nobody" is used

; guest account = pcguest

# this tells Samba to use a separate log file for each machine

# that connects

log file = /var/log/samba/%m.log

# Put a capping on the size of the log files (in Kb).

max log size = 50

# Use password server option only with security = server

# The argument list may include:

# password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]

# or to auto-locate the domain controller/s

# password server = *

; password server = <NT-Server-Name>

# Use the realm option only with security = ads

# Specifies the Active Directory realm the host is part of

; realm = MY_REALM

# Backend to store user information in. New installations should

# use either tdbsam or ldapsam. smbpasswd is available for backwards

# compatibility. tdbsam requires no further configuration.

; passdb backend = tdbsam

# Using the following line enables you to customise your configuration

# on a per machine basis. The %m gets replaced with the netbios name

# of the machine that is connecting.

# Note: Consider carefully the location in the configuration file of

# this line. The included file is read at that point.

; include = /usr/local/samba/lib/smb.conf.%m

# Configure Samba to use multiple interfaces

# If you have multiple network interfaces then you must list them

# here. See the man page for details.

; interfaces = 192.168.12.2/24 192.168.13.2/24

# Browser Control Options:

# set local master to no if you don't want Samba to become a master

# browser on your network. Otherwise the normal election rules apply

; local master = no

# OS Level determines the precedence of this server in master browser

# elections. The default value should be reasonable

; os level = 33

# Domain Master specifies Samba to be the Domain Master Browser. This

# allows Samba to collate browse lists between subnets. Don't use this

# if you already have a Windows NT domain controller doing this job

domain master = no

# Preferred Master causes Samba to force a local browser election on startup

# and gives it a slightly higher chance of winning the election

preferred master = no

# Enable this if you want Samba to be a domain logon server for

# Windows95 workstations.

domain logons = no

# if you enable domain logons then you may want a per-machine or

# per user logon script

# run a specific logon batch file per workstation (machine)

; logon script = %m.bat

# run a specific logon batch file per username

; logon script = %U.bat

# Where to store roving profiles (only for Win95 and WinNT)

# %L substitutes for this servers netbios name, %U is username

# You must uncomment the [Profiles] share below

; logon path = \\%L\Profiles\%U

# Windows Internet Name Serving Support Section:

# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server

; wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client

# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both

; wins server = w.x.y.z

# WINS Proxy - Tells Samba to answer name resolution queries on

# 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.

; wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names

# via DNS nslookups. The default is NO.

dns proxy = no

# These scripts are used on a domain controller or stand-alone

# machine to add or delete corresponding unix accounts

; add user script = /usr/sbin/useradd %u

; add group script = /usr/sbin/groupadd %g

; add machine script = /usr/sbin/adduser -n -g machines -c Machine -d /dev/null -s /bin/false %u

; delete user script = /usr/sbin/userdel %u

; delete user from group script = /usr/sbin/deluser %u %g

; delete group script = /usr/sbin/groupdel %g

smb ports = 139

# Desabilitando oplocks

# Permite ao samba usar gravacao e leitura de arquivos grandes, acima de 64Kb em uma unica requisicao samba

# Configura o maior bloco de dados que o samba ira tentar gravar de cada vez
