[Samba] authentication problem with winXP

Mon Dec 9 17:59:02 GMT 2002

Hi,

Here is my situation. I share several directories as public, and some
other that must be read-write but with authentication (it does not matter
is the client supplies the username or not, although it would be nice, but
the password is essential as not everybody must have write permission).
So what i first did was use the server with "security=user". WindowsXp
does not see my shares with this options set. It does not even ask for a
username and a password authentication (as it should just like when guest
account is disabled in XP). So then i went on putting "security=share" and
specifying in each non-public share :
public=no
writeable=yes
username=user ; for cases in which the client does not supply the
              ; username, but only the password
I also noticed i have to turn password encryption off in order to connect
to such shares with smbclient from linux. Still with encryption or not,
Windows XP refuses to connect to my share. What really drives me mad is
that (Windows Explorer) does not ask for a username/password but instead
asks anly for a password and connects with "MACHINENAME\Guest". I can
connect from smbclient with any user as long i supply the correct
password, from windows ..... no chance... :(
Where is the problem? I just want to share something with some sort of
authentication? Anybody got better or maybe simpler ideas?
I attached my smb.conf file in case somebody has the patience to take a
look. I'd really appreciate it. "E$" is the problem share.

So to put it simpler:
1)Why does windows not see my public shares when security=user
2)How can i share something and protect it with some sort of
authentication (and it should be accesible from Windows XP)

Thanks for reading my mail.

# 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]

# 1. Server Naming Options:
# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = P22

# netbios name is the name you will see in "Network Neighbourhood",
# but defaults to your hostname
;  netbios name = <name_of_this_server>

# server string is the equivalent of the NT Description field
   server string = de pe plaiurile de vanatoare vesnice...

# Message command is run by samba when a "popup" message is sent to it.
# The example below is for use with LinPopUp:
; message command = /usr/bin/linpopup "%f" "%m" %s; rm %s

# 2. Printing Options:
# CHANGES TO ENABLE PRINTING ON ALL CUPS PRINTERS IN THE NETWORK
# (as cups is now used in linux-mandrake 7.2 by default)
# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this
   printcap name = lpstat
   load printers = no

# 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, cups
   printing = cups

# Samba 2.2 supports the Windows NT-style point-and-print feature. To
# use this, you need to be able to upload print drivers to the samba
# server. The printer admins (or root) may install drivers onto samba.
# Note that this feature uses the print$ share, so you will need to 
# enable it below.
# This parameter works like domain admin group:
# printer admin = @<group> <user>
;   printer admin = @adm

# 3. Logging Options:
# this tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Put a capping on the size of the log files (in Kb).
   max log size = 50

# Set the log (verbosity) level (0 <= log level <= 10)
; log level = 3

# 4. Security and Domain Membership Options:
# 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. Do not enable this if (tcp/ip) name resolution does
# not work for all the hosts in your network.
;   hosts allow = 192.168.1. 192.168.2. 127.

# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used
;  guest account = pcguest

# Security mode. Most people will want user level security. See
# security_level.txt for details.
   security = share
# Use password server option only with security = server or security = domain
# When using security = domain, you should use password server = *
;   password server = <NT-Server-Name>
;   password server = *

# Password Level allows matching of _n_ characters of the password for
# all combinations of upper and lower case.
;  password level = 8
;  username level = 8

# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
# Encrypted passwords are required for any use of samba in a Windows NT domain
# The smbpasswd file is only required by a server doing authentication, thus
# members of a domain do not need one.
  encrypt passwords = no
  smb passwd file = /etc/samba/smbpasswd

# The following are needed to allow password changing from Windows to
# also update the Linux system password.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
#        the encrypted SMB passwords. They allow the Unix password
#        to be kept in sync with the SMB password.
;  unix password sync = Yes
;  passwd program = /usr/bin/passwd %u
;  passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n
;*passwd:*all*authentication*tokens*updated*successfully*

# Unix users can map to different SMB User names
  username map = /etc/samba/smbusers

# 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 = /etc/samba/smb.conf.%m

# Options for using winbind. Winbind allows you to do all account and
# authentication from a Windows or samba domain controller, creating
# accounts on the fly, and maintaining a mapping of Windows RIDs to unix uid's 
# and gid's. winbind uid and winbind gid are the only required parameters.
#
# winbind uid is the range of uid's winbind can use when mapping RIDs to uid's
;  winbind uid = 10000-20000
#
# winbind gid is the range of uid's winbind can use when mapping RIDs to gid's
;  winbind gid = 10000-20000
#
# winbind separator is the character a user must use between their domain
# name and username, defaults to "\"
;  winbind separator = +
#
# template homedir determines the home directory for winbind users, with 
# %D expanding to their domain name and %U expanding to their username:
;  template homedir = /home/%D/%U
#
# template shell determines the shell users authenticated by winbind get
;  template shell = /bin/bash

# 5. Browser Control and Networking Options:
# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

# 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 

# Configure remote browse list synchronisation here
#  request announcement to, or browse list sync from:
#       a specific host or from / to a whole subnet (see below)
;   remote browse sync = 192.168.3.25 192.168.5.255
# Cause this host to announce itself to local subnets here
;   remote announce = 192.168.1.255 192.168.2.44

# 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 = yes 

# 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 = yes

# 6. Domain Control Options:
# Enable this if you want Samba to be a domain logon server for 
# Windows95 workstations or Primary Domain Controller for WinNT and Win2k
;   domain logons = yes

# 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 roaming profiles for WinNT and Win2k
#        %L substitutes for this servers netbios name, %U is username
#        You must uncomment the [Profiles] share below
;   logon path = \\%L\Profiles\%U

# Where to store roaming profiles for Win9x. Be careful with this as it also
# impacts where Win2k finds it's /HOME share
; logon home = \\%L\%U\.profile

# The add user script is used by a domain member to add local user accounts
# that have been authenticated by the domain controller, or by the domain
# controller to add local machine accounts when adding machines to the domain.
# The script must work from the command line when replacing the macros,
# or the operation will fail. Check that groups exist if forcing a group.
# Script for domain controller for adding machines:
; add user script = /usr/sbin/useradd -d /dev/null -g machines -c 'Machine Account' -s /bin/false -M %u
# Script for domain member for adding local accounts for authenticated users:
; add user script = /usr/sbin/useradd -s /bin/false %u

# Domain groups:
# domain admin group is a list of unix users or groups who are made members
# of the Domain Admin group
; domain admin group = root @wheel
#
# domain guest groups is a list of unix users or groups who are made members
# of the Domain Guests group
; domain guest group = nobody @guest

# 7. Name Resolution Options:
# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# 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.
; name resolve order = wins lmhosts bcast

# 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 built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
   dns proxy = no 

# 8. File Naming Options:
# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis
;  preserve case = no
;  short preserve case = no
# Default case is normally upper case for all DOS files
;  default case = lower
# Be very careful with case sensitivity - it can break things!
;  case sensitive = no

# Enabling internationalization:
# you can match a Windows code page with a UNIX character set.
# Windows: 437 (US), 737 (GREEK), 850 (Latin1 - Western European),
# 852 (Eastern Eu.), 861 (Icelandic), 932 (Cyrillic - Russian),
# 936 (Japanese - Shift-JIS), 936 (Simpl. Chinese), 949 (Korean Hangul),
# 950 (Trad. Chin.).
# UNIX: ISO8859-1 (Western European), ISO8859-2 (Eastern Eu.),
# ISO8859-5 (Russian Cyrillic), KOI8-R (Alt-Russ. Cyril.)
# This is an example for french users:
;   client code page = 850
;   character set = ISO8859-1
