3.3 LDAP Population

3.4 Database Replication

Now its time to populate the database with our ldif that we edited to match our domain details as per section 3.2: Preload LDIF


Make sure LDAP is not running.

[root@node1]# vi /var/lib/ldap/DB_CONFIG

set_cachesize           0 150000000 1
set_lg_regionmax        262144
set_lg_bsize            2097152
set_flags               DB_LOG_AUTOREMOVE


This step is necessary if you are using delta-syncrepl as per section 2.1.2 slapd.conf Master delta-syncrepl Openldap2.3

Because we are using multiple databases on the Provider it is nessassary to place an additional DB_CONFIG file insite the database directory.

[root@node1]# mkdir /var/lib/ldap/accesslog
[root@node1]# cp /var/lib/ldap/DB_CONFIG /var/lib/ldap/accesslog


[root@node1]# cd /ldap-scripts/

[root@node1 scripts]# slapadd –b "dc=differentialdesign,dc=org"  -v -l preload-differentialdesign.ldif

[root@node1]# chown –R ldap.ldap /var/lib/ldap


The user to bind Samba to LDAP is defined in our smb.conf; this is sambaadmin’s password as set in samba preload-differentialdesign.ldif.

The entry in the preload-differentialdesign.ldif sambaadmin has a password “SambaAdmin”

dn: cn=sambaadmin,dc=differentialdesign,dc=org
objectClass: person
cn: sambaadmin
sn: sambaadmin
userPassword: SambaAdmin
[root@node1 scripts]# smbpasswd -w SambaAdmin
Setting stored password for "cn=sambaadmin,dc=differentialdesign,dc=org" in secrets.tdb

Adding initial users with the smbldap-tools: Skip to section 4.1: smbldap-tools and install on node1.

[root@node1 scripts]# cd /opt/IDEALX/sbin/

We must add the root user to start with.

[root@node1 sbin]# ./smbldap-useradd -m -a root
[root@node1 sbin]# ./smbldap-passwd root
Changing password for root
New password :
Retype new password
[root@node1 ]# smbpasswd -a

New SMB password:
Retype new SMB password:
Added user root.

[root@node1 sbin]# ./smbldap-groupmod -m root Domain\ Admins
adding user root to group Domain Admins
[root@node1 ~]# cd /opt/IDEALX/sbin/
[root@node1 sbin]# ./smbldap-useradd -m -a asender
[root@node1 sbin]#
[root@node1 sbin]# ./smbldap-passwd asender
Changing password for asender
New password :
Retype new password :
[root@node1 sbin]#
[root@node1 sbin]# smbpasswd asender
New SMB password:
Retype new SMB password:
[root@node1 sbin]#
[root@node1 sbin]# id asender
uid=1001(asender) gid=513(Domain Users) groups=513(Domain Users)


You are now ready to join a Windows machine to the domain with user ‘root’.

We will need to setup our BDC, Heartbeat and DRBD to match our configuration.
