How to Install OpenLDAP on MXLinux Latest

LDAP stands for Lightweight Directory Access Protocol, which is a client-server protocol for accessing directory services. OpenLDAP is an open-source implementation of the LDAP protocol, and it is widely used for managing user authentication, authorization, and user directories.

In this tutorial, we will see how to install and set up OpenLDAP on MXLinux Latest.

Step 1: Install OpenLDAP

Open the terminal and run the following command to install OpenLDAP:

sudo apt-get install slapd ldap-utils

This command will install the OpenLDAP server and utilities that we need to manage the LDAP directory.

Step 2: Configure OpenLDAP

After the installation, we need to configure OpenLDAP. Run the following command:

sudo dpkg-reconfigure slapd

This command will start the configuration wizard. Follow these steps to configure OpenLDAP:

• Choose your preferred hostname for the LDAP server.
• Select the domain name that you want to use for the LDAP directory.
• Choose the password for the LDAP administrator account.
• Choose the backend database for the LDAP directory. We recommend choosing the default option, BDB.
• Confirm the configuration settings.

Step 3: Test OpenLDAP

We can test the OpenLDAP installation and configuration by adding a test user to the directory. Run the following command to create a new file:

nano testuser.ldif

Paste the following content into the file:

dn: uid=testuser,dc=example,dc=com
objectClass: top
objectClass: account
objectClass: posixAccount
objectClass: shadowAccount
cn: Test User
uid: testuser
uidNumber: 10001
gidNumber: 10001
homeDirectory: /home/testuser
loginShell: /bin/bash
gecos: Test User
userPassword: {CRYPT}*
shadowLastChange: 18290
shadowMin: 0
shadowMax: 99999
shadowWarning: 7

Save and close the file.

Now, we can add the test user to the LDAP directory by running the following command:

ldapadd -x -D cn=admin,dc=example,dc=com -W -f testuser.ldif

This command will prompt you for the LDAP administrator password. Enter the password that you set in step 2.

If the user is added successfully, you will see a message like this:

adding new entry "uid=testuser,dc=example,dc=com"

Step 4: Access OpenLDAP

We can access our OpenLDAP server using the LDAP utilities. Run the following command to search for the test user:

ldapsearch -x -b dc=example,dc=com uid=testuser

This command will show the LDAP entry for the test user:

# testuser, example.com
dn: uid=testuser,dc=example,dc=com
objectClass: top
objectClass: account
objectClass: posixAccount
objectClass: shadowAccount
cn: Test User
uid: testuser
uidNumber: 10001
gidNumber: 10001
homeDirectory: /home/testuser
loginShell: /bin/bash
gecos: Test User
userPassword: {CRYPT}*
shadowLastChange: 18290
shadowMin: 0
shadowMax: 99999
shadowWarning: 7
