OpenLDAP is an Open Source LDAP implementation available for most platforms and Linux distributions. Its main component are:
- slapd- stand-alone LDAP daemon (server)
- libraries implementing the LDAP protocol, and
- utilities, tools, and sample clients.
Install slapd
Start by making sure your distro is up-to-date:
|
1 |
sudo apt update && sudo apt upgrade |
then install slapd and ldap-utils:
|
1 2 |
sudo apt install slapd ldap-tils |
During the installation, you will need to give a password for the administration account:
Configure slapd
In order to configure slapd you need to run:
|
1 2 |
sudo dpkg-reconfigure slapd |
On the first screen, select No:
Next, you will need to give the domain name you wish to use within the LDAP directory.
this will create a directory as follows:
|
1 2 |
dc=codeplumbers, dc=eu |
- Give the organization name (here codeplumbers) then you will be prompted for the admin password again. Type the password you setup earlier.
- Select the database format that will be used internally by slapd. I selected the default: MDB.
Finally, select wether you want the local database to be kept or delereed when slapd is uninstalled. I selected no. Slapd is now installed.
Test the installation
To verify your installation you can use the following command:
|
1 |
ldapsearch -x |
output:
|
1 |
pi@raspberrypi:~ $ ldapsearch -x # extended LDIF # # LDAPv3 # base <> (default) with scope subtree # filter: (objectclass=*) # requesting: ALL # # search result search: 2 result: 32 No such object # numResponses: 1 |
(the database is either empty or you need to use ldapsearch with authentication)
