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


Step1

Make sure LDAP is not running.

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


#DB_CONFIG
set_cachesize           0 150000000 1
set_lg_regionmax        262144
set_lg_bsize            2097152
set_flags               DB_LOG_AUTOREMOVE


Step2.

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


Step3.

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


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

added: "dc=differentialdesign,dc=org" (00000001)
added: "cn=Manager,dc=differentialdesign,dc=org" (00000002)
added: "cn=syncuser,dc=differentialdesign,dc=org" (00000003)
added: "cn=sambaadmin,dc=differentialdesign,dc=org" (00000004)
added: "cn=mailadmin,dc=differentialdesign,dc=org" (00000005)
added: "ou=Users,dc=differentialdesign,dc=org" (00000006)
added: "ou=People,ou=Users,dc=differentialdesign,dc=org" (00000007)
added: "ou=Computers,ou=Users,dc=differentialdesign,dc=org" (00000008)
added: "ou=Groups,dc=differentialdesign,dc=org" (00000009)
added: "ou=Domains,dc=differentialdesign,dc=org" (0000000a)
added: "sambaDomainName=DDESIGN,ou=Domains,dc=differentialdesign,dc=org" (0000000b)
added: "cn=Domain Admins,ou=Groups,dc=differentialdesign,dc=org" (0000000c)
added: "cn=Domain Users,ou=Groups,dc=differentialdesign,dc=org" (0000000d)
added: "cn=Domain Guests,ou=Groups,dc=differentialdesign,dc=org" (0000000e)
added: "cn=Domain Computers,ou=Groups,dc=differentialdesign,dc=org" (000000f)
added: "cn=Administrators,ou=Groups,dc=differentialdesign,dc=org" (00000010)
added: "cn=Account Operators,ou=Groups,dc=differentialdesign,dc=org" (00000011)
added: "cn=Print Operators,ou=Groups,dc=differentialdesign,dc=org" (00000012)
added: "cn=Backup Operators,ou=Groups,dc=differentialdesign,dc=org" (00000013)
added: "cn=Replicators,ou=Groups,dc=differentialdesign,dc=org" (00000014)


Step4.

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


Step5.

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


[root@node1 ~]# service ldap restart
Stopping slapd:                                      [  OK  ]
Stopping slurpd:                                     [  OK  ]

                                                     [  OK  ]
Starting slapd:                                      [  OK  ]

[root@node1 ~]# service smb restart
Shutting down SMB services:                         [  OK  ]
Shutting down NMB services:                         [  OK  ]
Starting SMB services:                              [  OK  ]
Starting NMB services:                              [  OK  ]


Step6.

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)


Step7

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.
