[+] Samba - uwierzytelnienie użytkowników w połączeniu z Windows

Post autor: waluszek »

Koledzy i Koleżanki

Walczę z sambą od Bóg wie jakiego czasu, przeczytałem już chyba wszystkie poradniki, i we wszystkich napisane jest prawie to samo.

M
ożliwe, że ja gdzieś popełniam błąd i go notorycznie powielam bo nie mogę ogarnąć samby a mianowicie:

Jest sobie serwer z Debianem 5.0.4, zainstalowana samba, ssh, webmin, i tym podobne.

Problem polega na tym, że jak ustawię sambę na uwierzytelnianie po prawach katalogów to działa, ale jak przestawię na uwierzytelnianie po użytkownikach to przy próbie wejścia z Windows na serwer z sambą, najpierw prosi o login i hasło, a jak już je podam to wyskakuje komunikat

Kod: Zaznacz cały

nazwa komputera/login
i prośba o ponowne wpisanie hasła i tak nie wiadomo dokąd.
Dodam, że użytkownik, o którym mowa istnieje w systemie i jest dodany do użytkowników samby.

Czy ktoś ma jakieś sugestie co zepsułem bo ja już wymiękam.

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# 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 most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

#======================= Global Settings =======================

[global]
log file = /var/log/samba/log.%m
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
obey pam restrictions = yes
encrypt passwords = true
passwd program = /usr/bin/passwd %u
passdb backend = tdbsam
dns proxy = no
server string = %h server
unix password sync = yes
workgroup = masterit
os level = 20
syslog = 0
security = user
panic action = /usr/share/samba/panic-action %d
max log size = 1000
pam password change = yes

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of

# server string is the equivalent of the NT Description field

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no

# 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

# This will prevent nmbd to search for NetBIOS names through DNS.

# What naming service and in what order should we use to resolve host names
# to IP addresses
; name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects

# Cap the size of the individual log files (in KiB).

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

# Do something sensible when Samba crashes: mail the admin a backtrace


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
# security = user

# You may wish to use password encryption. See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.


# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

########## Domains ###########

# Is this machine able to authenticate users. Both PDC and BDC
# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no
#
; domain logons = yes
#
# The following setting only takes effect if 'domain logons' is set
# It specifies the location of the user's profile directory
# from the client point of view)
# The following required a [profiles] share to be setup on the
# samba server (see below)
; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
# logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
; logon drive = H:
# logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the
# SAMR RPC pipe.
# The following assumes a "machines" group exists on the system
; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.
; add group script = /usr/sbin/addgroup --force-badname %g

########## Printing ##########

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

# lpr(ng) printing. You may wish to override the location of the
# printcap file
; printing = bsd
; printcap name = /etc/printcap

# CUPS printing. See also the cupsaddsmb(8) manpage in the
# cupsys-client package.
; printing = cups
; printcap name = cups

############ Misc ############

# 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
; include = /home/samba/etc/smb.conf.%m

# Most people will find that this option gives better performance.
# See smb.conf(5) and /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/speed.html
# for details
# You may want to add the following on a Linux system:
# SO_RCVBUF=8192 SO_SNDBUF=8192
# socket options = TCP_NODELAY

# The following parameter is useful only if you have the linpopup package
# installed. The samba maintainer and the linpopup maintainer are
# working to ease installation and configuration of linpopup and samba.
; message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s; rm %s' &

# Domain Master specifies Samba to be the Domain Master Browser. If this
# machine will be configured as a BDC (a secondary logon server), you
# must set this to 'no'; otherwise, the default behavior is recommended.
# domain master = auto

# Some defaults for winbind (make sure you're not using the ranges
# for something else.)
; idmap uid = 10000-20000
; idmap gid = 10000-20000
; template shell = /bin/bash

# The following was the default behaviour in sarge,
# but samba upstream reverted the default because it might induce
# performance issues in large organizations.
# See Debian bug #368251 for some of the consequences of *not*
# having this setting and smb.conf(5) for details.
; winbind enum groups = yes
; winbind enum users = yes

# Setup usershare options to enable non-root users to share folders
# with the net usershare command.

# Maximum number of usershare. 0 (default) means that usershare is disabled.
; usershare max shares = 100

No tak, pierwsze co ja robię w takiej sytuacji to (jako root):

Kod: Zaznacz cały

cp /etc/samba/smb.conf /etc/samba/smb.conf.bkp
a następnie:

Kod: Zaznacz cały

rm /etc/samba/smb.conf

Kod: Zaznacz cały

nano /etc/samba/smb.conf
i piszemy konfig od nowa. Spróbuj tak:

Kod: Zaznacz cały

[global]
    dos charset = 852
    unix charset = UTF8
    display charset = UTF8
    workgroup = GRUPA
    netbios name = server
    server string = server
    interfaces = eth0
    security = user
    update encrypted = Yes
    map to guest = Bad User
    null passwords = Yes
    log file = /var/log/samba/log.%m
     os level = 65
     wins support = Yes

[programy]
writeable = yes
        valid users = waluszek
        user = waluszek
        path = /dane/programy[I]/[/I]
        browsable = yes
        writeable = yes
        public = yes
        write list = waluszek
Pamiętaj o znaku / przy ścieżce path= gdyż samba czasem ma problemy jeśli w ścieżce brakuje go na końcu.

PS, I jeszcze jedno: rozumiem że użytkownik waluszek jest dodany do samby?

Więc konfig działa ale jakoś dziwnie bo dla użytkownika waluszek nie chce hasła.
Jak wpisuje nazwę i hasło to jest błąd.

Ale jak wpiszę samą nazwę to wszystko jest w porządku.

Poza tym wprowadziłem nowego użytkownika z innym katalogiem i tu jest problem bo nie działa ani na samą nazwę ani na nazwę + hasło.
Pomimo, że ustawienia są identyczne a użytkownik jest dodany do samby.

Jakimi poleceniami dodać użytkownika ,,linux'' do samby?
Używam webmina ale mam wrażenie, że on jakieś swoje śmieci wrzuca do konfiga samby.

Chcę to w końcu zrozumieć bo bawię się z tym co najmniej rok jak nie dłużej
gdzieś popełniam błąd ale gdzie?

Owszem działa ale tylko dla użytkownika waluszek.

Dodałem kolejnego użytkownika dominika i ten użytkownik nie może wejść, choć dodany jest tak samo jak waluszek.

Gdzieś jeszcze jest błąd?
