[Samba] doubt in samba-ldap configuration
Hello group,
I am trying to configure ldap backend to samba.
My samba and ldap machines are on different machines.
I am using samba3.0.22 and openldap-2.3.11.
I got two smb.conf files.
One in /etc/samba/smb.conf and another in
/usr/share/doc/samba-3.0.22/examples/LDAP/smbldap-tools-0.9.1/smb.conf.
Now the problem is when iam using 2nd smb.conf,
smbclient is showing the share info. for any user, i
mean if we give no username and wrong passwd it is
showing shares.
But when i use the 1st smb.conf file, smbclient is
giving
NT_STATUS_FAILED error, for all ldap users.
I am giving the two files's contents here.
Pls tell me the reason why it is behaving like that.
Also i was able to add samba users into ldap servers.
Pls let me know that existing ldap users and users i
added under objectclass sambaSambAccount are different
or same.If different, pls let me know how to give
username and password in ldif file.
contents of/etc/samba/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
#
# 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.

"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

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!

for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts
or via WINS.

queries on

work there must be

is NO.
