Start with installing the necessary packages:

You will be prompted to answer some questions:

• Omit OpenLDAP server configuration?
  Choose “No” so a basic configuration will be done.
• DNS domain name:
  This is up to you. This automatically constructs the root entry of the LDAP tree. To be consistent in this module, we should specify test.org.
• Organization name:

• Administrator password:
  The password of the LDAP administrator, remember it!
• Database backend to use:
  Use the default of HDB.
• Do you want the database to be removed when slapd is purged? Use the default.
• Allow LDAPv2 protocol? Use the default.

Next, edit “/etc/ldap/ldap.conf”. This file should be shared by all LDAP clients:

The first line simply helps to save some typing because it assumes all entries have the common ending of dc=test,dc=org. The second line tells an LDAP client where to find the LDAP server. In this case, we specify an IP address. It can be a host name as long as it can be resolved.

We are almost ready! Now edit “/etc/ldap/slapd.conf” and locate the line that says “index objectClass eq”, and append the following line as a new line and save the file:

Now we are ready to restart the LDAP server. Execute the following commands:
