Openldap Server configuration and user creation

OpenLdap

OpenLDAP is a free, open-source implementation of the Lightweight Directory Access Protocol (LDAP) developed by the OpenLDAP Project.

Installation

You can install openldap with the following command

sudo apt install slapd ldap-utils

You can reconfigure the openldap server with the following command

sudo dpkg-reconfigure slapd

You can reconfigure the cn=admin and domain as nitesh.com . Please don't forgot to remember the password that you have entered for the cn and domain creation

This is what the dc=nitesh,dc=com DIT looks like:

ldapsearch -x -LLL -H ldap:/// -b dc=nitesh,dc=com dn

dn: dc=nitesh,dc=com
dn: cn=admin,dc=nitesh,dc=com

User Creation

Initially we have to create a organization unit. You can create ou by adding this openldap_ou.ldif

dn: ou=openldap,dc=nitesh,dc=com
dc: openldap
objectClass: dcObject
objectClass: organizationalUnit
ou: openldap

Use below command for adding ou to this ldap database

ldapadd -x  -D "cn=admin,dc=nitesh,dc=com" -W  -f openldap_ou.ldif

Create users for OpenLdap. Initially we have to create openldap_user1.ldif

dn: uid=openldap_user1,ou=openldap,dc=nitesh,dc=com
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
uid: openldap_user1
sn: OLUser1
givenName: User1
cn: openldap_user1
displayName: openldap_user1
uidNumber: 1810
gidNumber: 1700
userPassword: openldap_user1
gecos: Openldap User1
homeDirectory: /home/openldap_user1

Add user with following command

ldapadd -x  -D "cn=admin,dc=nitesh,dc=com" -W  -f openldap_user1.ldif

You can check with ldapsearch command if the user is added to the database or not

ldapsearch -h localhost -x  -D "cn=admin,dc=nitesh,dc=com" -W
