<h2><a id="htoc1"></a>1 Introduction</h2>
<a id="sec:intro"></a> Smbldap-tools is a set of
scripts designed to help integrate Samba and a LDAP directory. They
target both users and administrators of Linux systems.
Users can change their password in a way similar to the standard
``passwd'' command.
Administrators can perform user and group management command line
actions and synchronise Samba account management
consistently.
This document presents:
<ul>
<li>a detailled view of the smbldap-tools scripts</li>
<li>a step by step explanation of how to set up a Samba3 domain
controller</li>
</ul>
<h3><a id="htoc2"></a>1.1 Software
requirements</h3>
The smbldap-tools have been developped and tested with the
following configuration :
<ul>
<li><em>Linux</em> RedHat 9 (be should work
on any <em>Linux</em> distribution)</li>
<li>Samba release 3.0.2pre1,</li>
<li>OpenLDAP release 2.1.22</li>
<li>Microsoft Windows NT 4.0, Windows 2000
and Windows XP Workstations and Servers,</li>
</ul>
This guide applies to smbldap-tools
<em>Release</em>: 0.8.7 .
<h3><a id="htoc3"></a>1.2 Updates of this
document</h3>

<h2><a id="htoc5"></a>2 Installation</h2>
<h3><a id="htoc6"></a>2.1 Requirements</h3>
The main requirement for using smbldap-tools are the two perl
module: Net::LDAP and Crypt::SmbHash. In most cases, you'll also
need the IO-Socket-SSL Perl module to use TLS functionnality.
If you want samba to call the scripts so that you can use the User
Manager (or any other) under MS-Windows (to add, delete modify
users and groups), Samba must be installed
on the same computer. Finally, OpenLDAP can
be installed on any computer. Please check that it can be contacted
by a standard LDAP client software.
Samba and OpenLDAP
installations will not be discussed here. You can consult the howto
also available on the project page (<a href="http://samba.IDEALX.org">http://samba.IDEALX.org</a>).
Altought is has been written for Samba2, most of its content still
apply to Samba3. The main difference stands in LDAP schema's
definitions.
<h3><a id="htoc7"></a>2.2 Installation</h3>
An archive of the smbldap-tools scripts can
be downloaded on our project page <a href="http://samba.IDEALX.org/">http://samba.IDEALX.org/</a>.
Archive and RedHat packages are available.
If you are upgrading, look at the INSTALL file or read the
link <a href="#faq::error::add::user">6.13</a>.
<a id="htoc8"></a>2.2.1 Installing from
rpm
To install the scripts on a RedHat system, download the RPM package
and run the following command:
<pre>
rpm -Uvh smbldap-tools-0.8.5-1.i386.rpm
</pre>
<a id="htoc9"></a>2.2.2 Installing from a
tarball
On non RedHat system, download a source archive of the scripts. The
current archive is smbldap-tools-0.8.5.tar.gz. Uncompress
it and copy all of the Perl scripts in /usr/local/sbin
directory, and the two configuration files in
/etc/opt/IDEALX/smbldap-tools/ directory:
<pre>
mkdir /etc/opt/IDEALX/smbldap-tools/
cp *.conf /etc/opt/IDEALX/smbldap-tools/
cp smbldap-* /usr/local/sbin/
</pre>
The configuration is now based on two differents files:
<ul>
<li>smbldap.conf: define global parameter</li>
<li>smbldap_bind.conf: define an administrative account to
bind to the directory</li>
</ul>
The second file <strong>must</strong> be readable only for 'root', as it
contains credentials allowing modifications on all the directory.
Make sure the files are protected by running the following
commands:
<pre>
chmod 644 /etc/opt/IDEALX/smbldap-tools/smbldap.conf
chmod 600 /etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf
</pre>
<h2><a id="htoc10"></a>3 Configuring the
smbldap-tools</h2>
As mentioned in the previous section, you'll have to update two
configuration files. The first (smbldap.conf) allows you
to set global parameter that are readable by everybody, and the
second (smbldap_bind.conf) defines two administrative
accounts to bind to a slave and a master ldap server: this file
must thus be readable only by root.
A script is named configure.pl can help you to set their
contents up. It is located in the tarball downloaded or in the
documentation directory if you got the RPM archive (see
/usr/share/doc/smbldap-tools/). Just invoke it:
<pre>
/usr/share/doc/smbldap-tools/configure.pl
</pre>
It will ask for the default values defined in your
smb.conf file, and will update the two configuration files
used by the scripts. Note that you can stop the script at any
moment with the Crtl-c keys.
Before using this script :
<ul>
<li>the two configuration files <strong>must</strong> be present in the
/etc/opt/IDEALX/smbldap-tools/ directory</li>
<li>check that samba is configured and running, as the script will
try to get your workgroup's domain secure id (SID).</li>
</ul>
In those files are parameters are defined like this:
<pre>
key="value"
</pre>
Full example configuration files can be found at <a href="#configuration::files">8.1</a>.
<h3><a id="htoc11"></a>3.1 The smbldap.conf
file</h3>
This file is used to define parameters that can be readable by
everybody. A full example file is available in section <a href="#configuration::file::smbldap">8.1.1</a>.
Let's have a look at all available parameters.

<li>Remark: you can get the SID for your domain using the net
getlocalsid command. Samba must be up and running for this to
work (it can take <strong>several</strong> minutes for a Samba server to
correctly negotiate its status with other network servers).</li>

<h3><a id="htoc12"></a>3.2 The smbldap_bind.conf
file</h3>
This file is only used by <em>root</em> to modify the content of the
directory. It contains distinguised names and credentials to
connect to both the master and slave directories. A full example
file is available in section <a href="#configuration::file::smbldap::bind">8.1.2</a>.
Let's have a look at all available parameters.
<ul>
<li>slaveDN : distinguished name used to bind to the slave
server
<ul>
<li>Example 1: slaveDN="cn=Manager,dc=idealx,dc=com"</li>
<li>Example 2: slaveDN=""</li>
<li>Remark: this can be the manager account of the directory or any
LDAP account that has sufficient permissions to read the full
directory (Slave directory is only used for reading). Anonymous
connections uses the second example form.</li>
</ul>
</li>
<li>slavePw : the credentials to bind to the slave server
<ul>
<li>Example 1: slavePw="secret"</li>
<li>Example 2: slavePw=""</li>
<li>Remark: the password must be stored here in clear form. This
file must then be readable only by root! All anonymous connections
use the second form provided in our example.</li>
</ul>
</li>
<li>masterDN : the distinguished name used to bind to the
master server
<ul>
<li>Example: masterDN="cn=Manager,dc=idealx,dc=com"</li>
<li>Remark: this can be the manager account of the directory or any
LDAP account that has enough permissions to modify the content of
the directory. Anonymous access does not make any sense here.</li>
</ul>
</li>
<li>masterPw : the credentials to bind to the master
server
<ul>
<li>Example: masterPw="secret"</li>
<li>Remark: the password must be in clear text. Be sure to protect
this file against unauthorized readers!</li>
</ul>
</li>
</ul>
<h2><a id="htoc13"></a>4 Using the scripts</h2>
<h3><a id="htoc14"></a>4.1 Initial directory's
population</h3>
You can initialize the LDAP directory using the
smbldap-populate script. To do that, the account defined
in the /etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf to
access the master directory <strong>must</strong> must be the manager account
defined in the directory configuration. On RedHat system, this file
is /etc/openldap/slapd.conf and the account is defined
with
<pre>
rootdn "cn=Manager,dc=idealx,dc=com"
rootpw secret
</pre>
The smbldap_bind.conf file must then be configured so that
the parameters to connect to the master LDAP server match the
previous ones:
<pre>
masterDN="cn=Manager,dc=idealx,dc=com"
masterPw="secret"

Table 1: Options available for the
smbldap-populate script
<a id="table::populate"></a>
<br/>
In the more general case, to set up your directory, simply use the
following command:
<pre>
[root@etoile root]# smbldap-populate
Using builtin directory structure
adding new entry: dc=idealx,dc=com
adding new entry: ou=Users,dc=idealx,dc=com
adding new entry: ou=Groups,dc=idealx,dc=com
adding new entry: ou=Computers,dc=idealx,dc=com
adding new entry: ou=Idmap,dc=idealx,dc=org
adding new entry: cn=NextFreeUnixId,dc=idealx,dc=org
adding new entry: uid=Administrator,ou=Users,dc=idealx,dc=com
adding new entry: uid=nobody,ou=Users,dc=idealx,dc=com
adding new entry: cn=Domain Admins,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Domain Users,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Domain Guests,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Print Operators,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Backup Operators,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Replicator,ou=Groups,dc=idealx,dc=com
adding new entry: cn=Domain Computers,ou=Groups,dc=idealx,dc=com
</pre>
After this step, if you don't want to use the
cn=Manager,dc=idealx,dc=com account anymore, you can
create a dedicated account for Samba and the smbldap-tools. See
section <a href="#change::manager">8.2</a> for more details.
The cn=NextFreeUnixId,dc=idealx,dc=org entry is only used
to defined the next uidNumber and gidNumber available for creating
new users and groups. The default values for those numbers are
1000. You can change it with the -u and -g
option. For example, if you want the first available value for
uidNumber and gidNumber to be set to 1500, you can use the
following command :
<pre>
smbldap-populate -u 1550 -g 1500
</pre>
<h3><a id="htoc15"></a>4.2 User management</h3>

Table 6: Options available for the
smbldap-groupadd script
<a id="table::add::group"></a>
<br/>
<a id="htoc21"></a>4.3.2 Removing a group
To remove the group named group1, just use the following
command :
<pre>
smbldap-userdel group1
</pre>
<h3><a id="htoc22"></a>4.4 Adding a interdomain
trust account</h3>
<a id="trust::account"></a> To add an
interdomain trust account to the primary controller
<em>trust-pdc</em>, use the -i option of
smbldap-useradd as follows :
<pre>
[root@etoile root]# smbldap-useradd -i trust-pdc
New password : *******
Retype new password : *******
</pre>
The script will terminate asking for a password for this trust
account. The account will be created in the directory branch where
all computer accounts are stored (ou=Computers by
default). The only two particularities of this account are that you
are setting a password for this account, and the flags of this
account are [I ].
<h2><a id="htoc23"></a>5 Samba and the smbldap-tools
scripts</h2>
<h3><a id="htoc24"></a>5.1 General
configuration</h3>
Samba can be configured to use the smbldap-tools scripts. This allows administrators to
add, delete or modify user and group accounts for Microsoft Windows operating systems using, for example,
User Manager utility under MS-Windows. To enable the use of this
utility, samba needs to be configured correctly. The
smb.conf configuration file must contain the following
directives :
<pre>
ldap delete dn = Yes
add user script = /usr/local/sbin/smbldap-useradd -m "%u"
add machine script = /usr/local/sbin/smbldap-useradd -w "%u"
add group script = /usr/local/sbin/smbldap-groupadd -p "%g"
add user to group script = /usr/local/sbin/smbldap-groupmod -m "%u" "%g"
delete user from group script = /usr/local/sbin/smbldap-groupmod -x "%u" "%g"
set primary group script = /usr/local/sbin/smbldap-usermod -g "%g" "%u"
</pre>
Remark: the two directives delete user script et
delete group script can also be used. However, an error
message can appear in User Manager even if the operations actually
succeed. If you want to enable this behaviour, you need to add
<pre>
delete user script = /usr/local/sbin/smbldap-userdel "%u"
delete group script = /usr/local/sbin/smbldap-groupdel "%g"
</pre>
<h3><a id="htoc25"></a>5.2 Migrating an NT4 PDC to
Samba3</h3>
The account migration procedure becomes really simple when samba is
configured to use the smbldap-tools. Samba
configuration (smb.conf file) must contain the directive defined
above to properly call the script for managing users, groups and
computer accounts. The migration process is outlined in the chapter
30 of the samba howto <a href="http://sambafr.idealx.org/samba/docs/man/Samba-HOWTO-Collection/NT4Migration.html">
http://sambafr.idealx.org/samba/docs/man/Samba-HOWTO-Collection/NT4Migration.html</a>.
<h2><a id="htoc26"></a>6 Frequently Asked
Questions</h2>
<h3><a id="htoc27"></a>6.1 How can i use old
released uidNumber and gidNumber ?</h3>
There are two way to do this :
<ul>
<li>modify the cn=NextFreeUnixId,dc=idealx,dc=org and
change the uidNumber and/or gidNumber value. This
must be done manually. For example, if you want to use all
available uidNumber and gidNumber higher then 1500, you need to
create a update-NextFreeUnixId.ldif file containing :
<pre>
dn: cn=NextFreeUnixId,dc=idealx,dc=org
changetype: modify
uidNumber: 1500
gidNumber: 1500
</pre>
and then update the directory :
<pre>
ldapmodify -x -D "cn=Manager,dc=idealx,dc=org" -w secret -f update-NextFreeUnixId.ldif
</pre></li>
<li>use the -u or -g option to the script you
need to set the value you want to use</li>
</ul>
<h3><a id="htoc28"></a>6.2 I always have this error:
"Can't locate IO/Socket/SSL.pm"</h3>
This happens when you want to use a certificate. In this case, you
need to install the IO-Socket-SSL Perl module.
<h3><a id="htoc29"></a>6.3 I can't initialize the
directory with smbldap-populate</h3>
When I want to initialize the directory using the
smbldap-populate script, I get
<pre>
[root@slave sbin]# smbldap-populate.pl
Using builtin directory structure
adding new entry: dc=IDEALX,dc=COM
Can't call method "code" without a package or object reference at
/usr/local/sbin/smbldap-populate.pl line 270, <GEN1> line 2.
</pre>
Answer: check the TLS configuration
<ul>
<li>if you don't want to use TLS support, set the
/etc/opt/IDEALX/smbldap-tools/smbldap.conf file with
<pre>
ldapSSL="0"
</pre></li>
<li>if you want TLS support, set the
/etc/opt/IDEALX/smbldap-tools/smbldap.conf file with
<pre>
ldapSSL="1"
</pre>
and check that the directory server is configured to accept TLS
connections.</li>
</ul>
<h3><a id="htoc30"></a>6.4 I can't join the domain
with the root account</h3>
<ul>
<li>check that the root account has the sambaSamAccount
objectclass</li>
<li>check that the directive add machine script is present
and configured</li>
</ul>
<h3><a id="htoc31"></a>6.5 I have the
sambaSamAccount but i can't logged in</h3>
Check that the sambaPwdLastSet attribute is not null
(equal to 0)
<h3><a id="htoc32"></a>6.6 I want to create machine
account on the fly, but it does not works or I must do it
twice</h3>
<ul>
<li>The script defined with the add machine script must
not add the sambaSAMAccount objectclass of the machine
account. The script must only add the Posix machine account. Samba
will add the sambaSAMAccount when joining the domain.</li>
<li>Check that the add <strong>machine</strong> script is present in
samba configuration file.</li>
</ul>
<h3><a id="htoc33"></a>6.7 I can't manage the Oracle
Internet Database</h3>
If you have an error message like :
<pre>
Function Not Implemented at /usr/local/sbin/smbldap_tools.pm line 187.
Function Not Implemented at /usr/local/sbin/smbldap_tools.pm line 627.
</pre>
For Oracle Database, all attributes that will be resquested to the
directory must be indexed. Add a new index for samba attributes and
make sure that the following attributes are also indexed :
uidNumber, gidNumber, memberUid, homedirectory, description,
userPassword ...
<h3><a id="htoc34"></a>6.8 The directive passwd
program = /usr/local/sbin/smbldap-passwd -u %u is not called,
or i got a error message when changing the password from
windows</h3>
The directive is called if you also set unix password sync =
Yes. Notes:
<ul>
<li>if you use OpenLDAP, none of those two options are needed. You
just need ldap passwd sync = Yes.</li>
<li>the script called here must only update the
userPassword attribute. This is the reason of the
-u option. Samba passwords will be updated by samba
itself.</li>
<li>the passwd chat directive must match what is prompted
when using the smbldap-passwd command</li>
</ul>
<h3><a id="htoc35"></a>6.9 New computers account

# just use the same server for slaveLDAP and masterLDAP.
# Those two servers declarations can also be used when you have
# . one master LDAP server where all writing operations must be done

<h3><a id="htoc47"></a>8.2 Changing the
administrative account (ldap admin dn in smb.conf
file)</h3>
<a id="change::manager"></a> If you don't
want to use the cn=Manager,dc=idealx,dc=com account
anymore, you can create a dedicated account for Samba and the
smbldap-tools scripts. To do this, create an account named
<em>samba</em> as follows (see section <a href="#add::user">4.2.1</a>
for a more detailed syntax) :
<pre>
smbldap-useradd -s /bin/false -d /dev/null -P samba
</pre>
This command will ask you to set a password for this account. Let's
set it to <em>samba</em> for this example. You then need to modify
configuration files:
<ul>
<li>file /etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf
<pre>
slaveDN="uid=samba,ou=Users,dc=idealx,dc=com"
slavePw="samba"
masterDN="uid=samba,ou=Users,dc=idealx,dc=com"
masterPw="samba"
</pre></li>
<li>file /etc/samba/smb.conf
<pre>
ldap admin dn = uid=samba,ou=Users,dc=idealx,dc=com
</pre>
don't forget to also set the samba account password in
secrets.tdb file :
<pre>
smbpasswd -w samba
</pre></li>
<li>file /etc/openldap/slapd.conf: give to the
<em>samba</em> user permissions to modify some attributes: this user
needs to be able to modify all the samba attributes and some others
(uidNumber, gidNumber ...) :
<pre>
# users can authenticate and change their password
access to attrs=userPassword,sambaNTPassword,sambaLMPassword,sambaPwdLastSet,sambaPwdMustChange
by dn="uid=samba,ou=Users,dc=idealx,dc=com" write
by self write
by anonymous auth
by * none
# some attributes need to be readable anonymously so that 'id user' can answer correctly
access to attrs=objectClass,entry,gecos,homeDirectory,uid,uidNumber,gidNumber,cn,memberUid
by dn="uid=samba,ou=Users,dc=idealx,dc=com" write
by * read
# somme attributes can be writable by users themselves
access to attrs=description,telephoneNumber

# some attributes need to be writable for samba
access to attrs=cn,sambaLMPassword,sambaNTPassword,sambaPwdLastSet,sambaLogonTime,sambaLogoffTime,sambaKickoffTime,sambaPwdCanChange,sambaPwdMustChange,sambaAcctFlags,displayName,sambaHomePath,sambaHomeDrive,sambaLogonScript,sambaProfilePath,description,sambaUserWorkstations,sambaPrimaryGroupSID,sambaDomainName,sambaSID,sambaGroupType,sambaNextRid,sambaNextGroupRid,sambaNextUserRid,sambaAlgorithmicRidBase
