Samba Primary Domain Controller with Open-LDAP HowTo


Scenario:

We are going to configure a Linux based Primary Domain Controller using Samba
which will authenticate the domain users through LDAP

Domain Name : company.xy

Hostname IP-Address OPerating System

dns.company.xy 192.168.3.135 RedHat-5
ldap.company.xy 192.168.3.140 CentOS-5.3
client1.company.xy 192.168.3.145 Windows-XP-Service Pack2
client2.company.xy 192.168.3.150 Windows-XP-Service Pack2

Default Gateway os all the servers is 192.168.3.1 which is the IP of DSL router
for Internet

Required Packages: version number:
1).DNS packages>>
bind 9.3 or higher
bind-chroot 9.3 0r higher
bind-utils 9.3 0r higher
bind-libs 9.3 0r higher

2).OpenLDAP packages>>
openldap 2.3 or higher
openldap-clients 2.3 or higher
openldap-devel 2.3 or higher
compat-openldap 2.3 or higher
python-ldap 2.2 or higher
ldapjdk 4.18 or higher
php-ldap 5.1 or higher
nss_ldap 253-17

3).Samba packages>>
samba 3.0 or higer
samba-common 3.0 or higer
samba-client 3.0 or higer

4).samba-ldap tools>> Download Link for Perl Packages:  http://dag.wieers.com/rpm/packages/
perl-Crypt-SmbHash 0.12-1.2.el5

Download Link: http://nchc.dl.sourceforge.net/project/smbldap-tools/smbldap-tools/0.9.2/smbldap-tools-0.9.2-1a.noarch.rpm

Note: currently we will disable SELINUX,Firewall,Iptables on each linux machine
and after successful completion of our task, we will add ports tcp 53 for DNS
and tcp 389 for ldap to make use of firewalls.
After installing all the packages, we will configure DNS with ldap support.

lets check network settings

[root@dns /]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=dns

[root@dns /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0C:29:D4:54:7D
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.3.135
GATEWAY=192.168.3.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes

[root@dns /]# vim /etc/resolv.conf
nameserver 192.168.3.135
search company.xy

[root@dns /]# /etc/init.d/network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
[root@dns /]#

DNS configuration:
[root@dns ~]# cd /var/named/chroot/etc/
[root@dns etc]# vim named.conf

options
{
directory "/var/named"; // the default
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";

};

zone "." IN {
type hint;
file "named.root";
};


zone "localhost" IN {
type master;
file "localhost.fwd";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "localhost.rev";
allow-update { none; };
};

zone "company.xy" IN {
type master;
file "company.xy.fwd";
allow-update { none; };
};

zone "3.168.192.in-addr.arpa" IN {
type master;
file "company.xy.rev";
allow-update { none; };
};


Now we will create the zone files
[root@dns etc]# cd /var/named/chroot/var/named/
Note: About any leading spaces in front of the lines in named.root: remove them!
Lines should start in a ;, . or character, not blanks.
[root@dns named]# vim named.root

now run the dns daemon i.e named

[root@dns named]# /etc/init.d/named start
Starting named: [ OK ]
[root@dns named]#

make it sure that named service will run automatically at startup

[root@dns named]# chkconfig --level 235 named on

now we will test our newly configured dns

[root@dns named]# nslookup

[root@dns named]#

Everything is fine Alhamdulillah

we are configuring a simple domain controller in this howto. You can allow
roaming profiles and home directories for domain users.

lets configure some directories referenced in /etc/samba/smb.conf
[root@ldap samba]# mkdir /home/samba
[root@ldap samba]# mkdir /home/samba/netlogon
[root@ldap samba]# mkdir /home/samba/profiles
[root@ldap samba]# chmod 1777 /home/samba/profiles [currently we
will not use profile feature]

Samba must know the ldap admin dn password so lets do it
[root@ldap samba]# smbpasswd -w secret
Setting stored password for "cn=Manager,dc=company,dc=xy" in secrets.tdb
[root@ldap samba]#

Now define the domain Secure ID (SID)
[root@ldap samba]# net getlocalsid
SID for domain LDAPSERVER is: S-1-5-21-2815000769-282395026-991120840
[root@ldap samba]#

Replace the raw SID in /etc/opt/IDEALX/smbldap-tools/smbldap.conf with above
mentioned SID.

make sure that smbldap scripts are placed in /usr/local/sbin
otherwise make symbolic link of each script in /usr/local/sbin as this path is
defined in smb.conf
[root@ldap samba]# cd /opt/IDEALX/sbin/
[root@ldap sbin]# ls
configure.pl smbldap-groupmod smbldap-populate smbldap-userdel
smbldap-usershow
smbldap-groupadd smbldap-groupshow smbldap_tools.pm smbldap-userinfo
smbldap-groupdel smbldap-passwd smbldap-useradd smbldap-usermod

[root@ldap sbin]# ln -s /opt/IDEALX/sbin/configure.pl
/usr/local/sbin/configure.pl
[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-groupadd
/usr/local/sbin/smbldap-groupadd
[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-groupdel

[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-usermod
/usr/local/sbin/smbldap-usermod
[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-usershow
/usr/local/sbin/smbldap-usershow


Now add the default base entries

[root@ldap /]# smbldap-populate
Populating LDAP directory for domain company.xy
(S-1-5-21-2815000769-282395026-991120840)
(using builtin directory structure)

adding new entry dc=company,dc=xy
adding new entry ou=Users,dc=company,dc=xy
adding new entry ou=Groups,dc=company,dc=xy
adding new entry ou=Computers,dc=company,dc=xy
adding new entry ou=Idmap,dc=company,dc=xy
adding new entry uid=root,ou=Users,dc=company,dc=xy
adding new entry uid=nobody,ou=Users,dc=company,dc=xy
adding new entry cn=Domain Admins,ou=Groups,dc=company,dc=xy
adding new entry cn=Domain Users,ou=Groups,dc=company,dc=xy
adding new entry cn=Domain Guests,ou=Groups,dc=company,dc=xy
adding new entry cn=Domain Computers,ou=Groups,dc=company,dc=xy
adding new entry cn=Administrators,ou=Groups,dc=company,dc=xy
adding new entry cn=Account Operators,ou=Groups,dc=company,dc=xy
adding new entry cn=Print Operators,ou=Groups,dc=company,dc=xy
adding new entry cn=Backup Operators,ou=Groups,dc=company,dc=xy
adding new entry cn=Replicators,ou=Groups,dc=company,dc=xy
adding new entry sambaDomainName=company.xy,dc=company,dc=xy

Please provide a password for the domain root:
Changing UNIX and samba passwords for root
New password:
Retype new password:
[root@ldap /]#

adding Domain Security Accounts
for this purpose we will create a ldif file and add the entries at once.
[root@ldap Desktop]# vim dsa.ldif

Enter LDAP Password:
adding new entry "ou=DSA,dc=company,dc=xy"

adding new entry "cn=samba,,ou=DSA,dc=company,dc=xy"

adding new entry "cn=nssldap,ou=DSA,dc=company,dc=xy"

adding new entry "cn=smbtools,ou=DSA,dc=company,dc=xy"

[root@ldap Desktop]#

Password of each security accoutn can be changed further by the following
command

[root@ldap Desktop]# ldappasswd -x -h localhost -D "cn=Manager,dc=company,dc=xy"
-s password -W cn=samba,ou=DSA,dc=company,dc=xy

now start samba server

[root@ldap Desktop]# /etc/init.d/smb start
Starting SMB services: [ OK ]
Starting NMB services: [ OK ]
[root@ldap Desktop]#

Now create a samba user account for UNIX and SAMBA

[root@ldap Desktop]# smbldap-useradd -a -m -c "Muhammad Farrukh Siddique"
mfarrukh
[root@ldap Desktop]# smbldap-passwd mfarrukh
Changing UNIX and samba passwords for mfarrukh
New password:
Retype new password:
[root@ldap Desktop]# useradd mfarrukh

Now create a machine trust account

[root@ldap Desktop]# smbldap-useradd -w client1

Machine trust accoutn must also be in /etc/passwd
[root@ldap Desktop]# useradd -d /dev/null -s /bin/false client1$
($ sign differentiate between user and machine accounts)

lets search a user account

Now Everything has been configured successfully.

Last step is to join domain.

Power ON xp machine

set the network settings according to this scenario these will be

IP Address: 192.168.3.145
Subnet Mask: 255.255.255.0
D.Gateway: 192.168.3.1
Primary DNS: 192.168.3.135

Right click on My Computer icon and go to the Properties
under Computer Name tab click on Change button and write the domain name
enter username: root and its password a welcome screen will appear.
Just restart the computer and enter with domain username.

Task completed successfully.

Samba Primary Domain Controller with Open-LDAP How-TO

written by: Muhammad Farrukh Siddique (LPIC)



Scenario:

We are going to configure a Linux based Primary Domain Controller using Samba
which will authenticate the domain users through LDAP

Domain Name : company.xy

Hostname IP-Address OPerating System

dns.company.xy 192.168.3.135 RedHat-5
ldap.company.xy 192.168.3.140 CentOS-5.3
client1.company.xy 192.168.3.145 Windows-XP-Service Pack2
client2.company.xy 192.168.3.150 Windows-XP-Service Pack2

Default Gateway os all the servers is 192.168.3.1 which is the IP of DSL router
for Internet

Required Packages: version number:
1).DNS packages>>
bind 9.3 or higher
bind-chroot 9.3 0r higher
bind-utils 9.3 0r higher
bind-libs 9.3 0r higher

2).OpenLDAP packages>>
openldap 2.3 or higher
openldap-clients 2.3 or higher
openldap-devel 2.3 or higher
compat-openldap 2.3 or higher
python-ldap 2.2 or higher
ldapjdk 4.18 or higher
php-ldap 5.1 or higher
nss_ldap 253-17

3).Samba packages>>
samba 3.0 or higer
samba-common 3.0 or higer
samba-client 3.0 or higer

4).samba-ldap tools>> Download Link for Perl Packages:
http://dag.wieers.com/rpm/packages/
perl-Crypt-SmbHash 0.12-1.2.el5
perl-Digest-SHA1 2.11-1.2.1

Download Link:
http://nchc.dl.sourceforge.net/project/smbldap-tools/smbldap-tools/0.9.2/smbldap-tools-0.9.2-1a.noarch.rpm

Note: currently we will disable SELINUX,Firewall,Iptables on each linux machine
and after successful completion of our task, we will add ports tcp 53 for DNS
and tcp 389 for ldap to make use of firewalls.
After installing all the packages, we will configure DNS with ldap support.

lets check network settings

[root@dns /]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=dns

[root@dns /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0C:29:D4:54:7D
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.3.135
GATEWAY=192.168.3.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes

[root@dns /]# vim /etc/resolv.conf
nameserver 192.168.3.135
search company.xy

[root@dns /]# /etc/init.d/network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]
[root@dns /]#

DNS configuration:
[root@dns ~]# cd /var/named/chroot/etc/
[root@dns etc]# vim named.conf

options
{
directory "/var/named"; // the default
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
memstatistics-file "data/named_mem_stats.txt";

};

zone "." IN {
type hint;
file "named.root";
};


zone "localhost" IN {
type master;
file "localhost.fwd";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "localhost.rev";
allow-update { none; };
};

zone "company.xy" IN {
type master;
file "company.xy.fwd";
allow-update { none; };
};

zone "3.168.192.in-addr.arpa" IN {
type master;
file "company.xy.rev";
allow-update { none; };
};


Now we will create the zone files
[root@dns etc]# cd /var/named/chroot/var/named/
Note: About any leading spaces in front of the lines in named.root: remove them!
Lines should start in a ;, . or character, not blanks.
[root@dns named]# vim named.root

now run the dns daemon i.e named

[root@dns named]# /etc/init.d/named start
Starting named: [ OK ]
[root@dns named]#

make it sure that named service will run automatically at startup

[root@dns named]# chkconfig --level 235 named on

now we will test our newly configured dns

[root@dns named]# nslookup

we are configuring a simple domain controller in this howto. You can allow
roaming profiles and home directories for domain users.

lets configure some directories referenced in /etc/samba/smb.conf
[root@ldap samba]# mkdir /home/samba
[root@ldap samba]# mkdir /home/samba/netlogon
[root@ldap samba]# mkdir /home/samba/profiles
[root@ldap samba]# chmod 1777 /home/samba/profiles [currently we
will not use profile feature]

Samba must know the ldap admin dn password so lets do it
[root@ldap samba]# smbpasswd -w secret
Setting stored password for "cn=Manager,dc=company,dc=xy" in secrets.tdb
[root@ldap samba]#

Now define the domain Secure ID (SID)
[root@ldap samba]# net getlocalsid
SID for domain LDAPSERVER is: S-1-5-21-2815000769-282395026-991120840
[root@ldap samba]#

Replace the raw SID in /etc/opt/IDEALX/smbldap-tools/smbldap.conf with above
mentioned SID.

make sure that smbldap scripts are placed in /usr/local/sbin
otherwise make symbolic link of each script in /usr/local/sbin as this path is
defined in smb.conf
[root@ldap samba]# cd /opt/IDEALX/sbin/
[root@ldap sbin]# ls
configure.pl smbldap-groupmod smbldap-populate smbldap-userdel
smbldap-usershow
smbldap-groupadd smbldap-groupshow smbldap_tools.pm smbldap-userinfo
smbldap-groupdel smbldap-passwd smbldap-useradd smbldap-usermod

[root@ldap sbin]# ln -s /opt/IDEALX/sbin/configure.pl
/usr/local/sbin/configure.pl
[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-groupadd
/usr/local/sbin/smbldap-groupadd

/usr/local/sbin/smbldap-usermod
[root@ldap sbin]# ln -s /opt/IDEALX/sbin/smbldap-usershow
/usr/local/sbin/smbldap-usershow


Now add the default base entries

[root@ldap /]# smbldap-populate

adding new entry "cn=smbtools,ou=DSA,dc=company,dc=xy"

[root@ldap Desktop]#

Password of each security accoutn can be changed further by the following
command

[root@ldap Desktop]# ldappasswd -x -h localhost -D "cn=Manager,dc=company,dc=xy"
-s password -W cn=samba,ou=DSA,dc=company,dc=xy

now start samba server

[root@ldap Desktop]# /etc/init.d/smb start
Starting SMB services: [ OK ]
Starting NMB services: [ OK ]
[root@ldap Desktop]#

Now create a samba user account for UNIX and SAMBA

[root@ldap Desktop]# smbldap-useradd -a -m -c "Muhammad Farrukh Siddique"
mfarrukh
[root@ldap Desktop]# smbldap-passwd mfarrukh
Changing UNIX and samba passwords for mfarrukh
New password:
Retype new password:
[root@ldap Desktop]# useradd mfarrukh

Now create a machine trust account

[root@ldap Desktop]# smbldap-useradd -w client1

Machine trust accoutn must also be in /etc/passwd
[root@ldap Desktop]# useradd -d /dev/null -s /bin/false client1$
($ sign differentiate between user and machine accounts)

lets search a user account

[root@ldap Desktop]# smbldap-usershow mfarrukh
