Installing OpenLDAP on CentOS 8

OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol (LDAP). It provides a centralized database for storing and managing directory information, such as user accounts, group memberships, and network resources.

Step 1: Install OpenLDAP

To install OpenLDAP on CentOS 8, follow these steps:

    $ sudo dnf install openldap openldap-servers openldap-clients
  

Step 2: Start and Enable OpenLDAP

After the installation, start and enable the OpenLDAP service:

    $ sudo systemctl start slapd
    $ sudo systemctl enable slapd
  

Step 3: Configure OpenLDAP

OpenLDAP configuration files are located in the /etc/openldap/ directory. The main configuration file is slapd.conf. Edit this file to customize your LDAP server settings:

    $ sudo vi /etc/openldap/slapd.conf
  

Step 4: Create LDAP Directory Structure

Create the LDAP directory structure by importing the default schema files:

    $ sudo slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d/
    $ sudo chown -R ldap:ldap /etc/openldap/slapd.d/
  

Step 5: Start LDAP Client

Finally, start the LDAP client service:

    $ sudo systemctl start slurpd
    $ sudo systemctl enable slurpd
  

Step 6: Verify OpenLDAP

To check if OpenLDAP is running, you can run the following command:

    $ sudo systemctl status slapd
  

You have successfully installed and configured OpenLDAP on CentOS 8. You can now use it to manage directory information for your applications, users, and resources.
