Step by Step Installation and Configuration OpenLDAP Server

Software: OS-Cent OS 4.4, openldap 2.2.13-6.4E System name: ldap.adminmart.com Domain name: adminmart.com System IP: 192.168.1.212

Note: Use your domain name and IP instead of adminmart

Easy steps for adding users: 1. Create unix user 2. Create unix user's ldap passwd file 3. Convert passwd.file to ldif file 4. Add ldap file to LDAP Directory using ldapadd

Step #1. Requirements

compat-openldap.i386 0:2.1.30-6.4E openldap-clients.i386 0:2.2.13-6.4E openldap-devel.i386 0:2.2.13-6.4E openldap-servers.i386 0:2.2.13-6.4E openldap-servers-sql.i386 0:2.2.13-6.4E


You can install them using the command:

yum install *openldap* -y


Step #2. Start the service

[root@ldap ~]# chkconfig --levels 235 ldap on [root@ldap ~]# service ldap start Step #3. Create LDAP root user password

[root@ldap ~]# slappasswd New password: Re-enter new password: {SSHA}cWB1VzxDXZLf6F4pwvyNvApBQ8G/DltW [root@ldap ~]# Step #4. Update /etc/openldap/slapd.conf for the root password

[root@ldap ~]# vi /etc/openldap/slapd.conf

  1. 68 database bdb
  2. 69 suffix "dc=adminmart,dc=com"
  3. 70 rootdn "cn=Manager,dc=adminmart,dc=com"
  4. 71 rootpw {SSHA}cWB1VzxDXZLf6F4pwvyNvApBQ8G/DltW

Step #5. Apply Changes

[root@ldap ~]# service ldap restart Step #6. Create test users

[root@ldap ~]# useradd test1 [root@ldap ~]# passwd test1 Changing password for user test1. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@ldap ~]# useradd test2 [root@ldap ~]# passwd test2 Changing password for user test2. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@ldap ~]# Note: Repeat the same for the rest of users Step #7. Migrate local users to LDAP

[root@ldap ~]# grep root /etc/passwd > /etc/openldap/passwd.root [root@ldap ~]# grep test1 /etc/passwd > /etc/openldap/passwd.test1 [root@ldap ~]# grep test2 /etc/passwd > /etc/openldap/passwd.test2 Note: Repeat the same for the rest of users Step #8. Update default settings on file /usr/share/openldap/migration/migrate_common.ph

  1. 71 $DEFAULT_MAIL_DOMAIN = "adminmart.com";
  2. 74 $DEFAULT_BASE = "dc=adminmart,dc=com";

Step #9. Convert passwd.file to ldif (LDAP Data Interchange Format) file

[root@ldap ~]# /usr/share/openldap/migration/migrate_passwd.pl /etc/openldap/passwd.root /etc/openldap/root.ldif [root@ldap ~]# /usr/share/openldap/migration/migrate_passwd.pl /etc/openldap/passwd.test1 /etc/openldap/test1.ldif [root@ldap ~]# /usr/share/openldap/migration/migrate_passwd.pl /etc/openldap/passwd.test2 /etc/openldap/test2.ldif Note: Repeat the same for the rest of users Step #10. Update root.ldif file for the "Manager" of LDAP Server

[root@ldap ~]# vi /etc/openldap/root.ldif

  1. 1 dn: uid=root,ou=People,dc=adminmart,dc=com
  2. 2 uid: root
  3. 3 cn: Manager
  4. 4 objectClass: account

Step #11. Create a domain ldif file (/etc/openldap/adminmart.com.ldif)

[root@ldap ~]# cat /etc/openldap/adminmart.com.ldif dn: dc=adminmart,dc=com dc: adminmart description: LDAP Admin objectClass: dcObject objectClass: organizationalUnit ou: rootobject

dn: ou=People, dc=adminmart,dc=com ou: People description: Users of adminmart objectClass: organizationalUnit

Step #12. Import all users in to the LDAP

Add the Domain ldif file

[root@ldap ~]# ldapadd -x -D "cn=Manager,dc=adminmart,dc=com" -W -f /etc/openldap/adminmart.com.ldif Enter LDAP Password: adding new entry "dc=adminmart,dc=com" adding new entry "ou=People, dc=adminmart,dc=com" [root@ldap ~]#

Add the Users

[root@ldap ~]# ldapadd -x -D "cn=Manager,dc=adminmart,dc=com" -W -f /etc/openldap/root.ldif Enter LDAP Password: adding new entry "uid=root,ou=People,dc=adminmart,dc=com" adding new entry "uid=operator,ou=People,dc=adminmart,dc=com" [root@ldap ~]#

[root@ldap ~]# ldapadd -x -D "cn=Manager,dc=adminmart,dc=com" -W -f /etc/openldap/test1.ldif Enter LDAP Password: adding new entry "uid=test1,ou=People,dc=adminmart,dc=com" [root@ldap ~]#

[root@ldap ~]# ldapadd -x -D "cn=Manager,dc=adminmart,dc=com" -W -f /etc/openldap/test2.ldif Enter LDAP Password: adding new entry "uid=test2,ou=People,dc=adminmart,dc=com" [root@ldap ~]#

Note: Repeat the same for the rest of users

Step #13. Apply Changes

[root@ldap ~]# service ldap restart

Step #14. Test LDAP Server It prints all the user information

[root@ldap ~]# ldapsearch -x -b 'dc=adminmart,dc=com' '(objectclass=*)'
