1. Install OpenLdap on Ubuntu.

   Note
   These instructions are based on Ubuntu 18.04.

2. In a terminal window, issue the following commands:

   Code Block
   sudo apt-get update sudo apt-get upgrade

3. In a terminal window, then issue the following command.

   Code Block
   sudo apt install slapd ldap-utils

4. Modify the default Directory Information Tree (DIT) suffix by changing the DIT to fit your company's network needs. For example,  dc=smab,dc=org. To do so, issue the following command.

   Code Block
   sudo dpkg-reconfigure slapd

5. Enter the administrator's password.

6. Add initial data to the LDAP database from a file and create a single entry. In a terminal window, issue the following command.

   Code Block

   vi ldap_data.ldif dn: ou=People,dc=smab,dc=org objectClass: organizationalUnit ou: People dn: ou=Groups,dc=smab,dc=org objectClass: organizationalUnit ou: Groups dn: cn=DEPARTMENT,ou=Groups,dc=smab,dc=org objectClass: posixGroup cn: SUBGROUP gidNumber: 5000 dn: uid=nciadevtest,ou=People,dc=smab,dc=org objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount uid: nciadevtest sn: Last name givenName: First name cn: nciadevtest displayName: Name uidNumber: 10000 gidNumber: 5000 userPassword: password gecos: Whole Name loginShell: /bin/bash homeDirectory: USERDIRECTORY

   Note
   In this .ldif file, we created two organizationalUnit values, People and Groups.

7. Add the entities for these OU values. One entity must be nciadevtest for NBIA. The uid and cn must be this name. NBIA uses cn to as the default authentication. Some software applications use uid to authenticate.

8. Add the following entities to the LDAP server.
   

   Code Block
   ldapadd -x -D cn=admin,dc=smab,dc=org -W -f ldap_data.ldif

9. Use this command to search the existing records. You can use the network loop IP address to test or use the real IP address.
   

   Code Block

   ldapsearch -x -LLL -h 127.0.0.1 -p 389 -D cn=admin,dc=smab,dc=org -w smab123456 -b dc=smab,dc=org 'uid=nciadevtest' cn givenName gidNumber Result: dn: uid=nciadevtest,ou=People,dc=smab,dc=org givenName: First Name cn: nciadevtest gidNumber: 5000 ldapsearch -x -LLL -h 69.71.4.10 -p 389 -D cn=admin,dc=smab,dc=org -w smab123456 -b dc=smab,dc=org 'cn=nciadevtest' uid givenName gidNumber Result: dn: uid=nciadevtest,ou=People,dc=smab,dc=org uid: nciadevtest givenName: First Name gidNumber: 5000

10. Add the records. The LDAP server configuration looks similar to the following.

    Code Block
    Title Value Base DN smab,dc=org Bind Admin admin,dc=smab,dc=org Bind Password Smab123456 User name for NBIA nciadevtest

LDAP administrator client.

Configuring the LDAP Administrator Client

You can add, modify, or remove records to or from the LDAP server in several ways.

• On a Linux server, use phpldapadmin to maintain the LDAP server.

...

• Refer to the following links to install phpldapadmin. (Note that phpldapadmin is not updated. There are some errors with php7.0 +).
  • https://www.techrepublic.com/article/how-to-install-phpldapadmin-on-ubuntu-18-04/
  • https://www.techrepublic.com/article/how-to-install-and-configure-ldap-and-phpldapadmin/

...

• Use a Windows LDAP client such as Softerra LDAP Administrator to access the remote LDAP server.

...

To How to use Softerra LDAP Administrator

1. Create a new profile.
2. Add the server host (IP or domain), Base DN, and port.
3. Add the bind admin information.

You can use the LDAP client to create/, delete/, and modify the entities with this information. Otherwise, you only have the read permission.

Troubleshooting

...

The OpenLdap can be installed on Ubuntu Server. The phpldapadmin also can work. The ldapsearch also can search the user information.
But when I tried to use LDAP client to access this LDAP server. The connection is timeout. There is no any response from LDAP server even if I enabled all ports.
I think the reason is the Ubuntu Server is blocked the LDAP be default (Maybe firewall reason). Currently, I haven’t find the way to solve this issue yet.

When I installed OpenLDAP on Ubuntu (Desktop version). All LDAP function works by default. There is no any issues. I can use any LDAP client tool to access the remote LDAP server, which is on Ubuntu Desktop.

NBIA LDAP settings.

1. In nbia.properties (Tomcat7.0/lib/nbia.properties)
