In this tutorial, we will guide you through the process of installing OpenLDAP on FreeBSD Latest. OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol (LDAP) that allows you to access, manage, and share information about network resources such as users, groups, hosts, and services.
Before installing OpenLDAP, update the FreeBSD system to the latest version:
sudo pkg update && sudo pkg upgrade
To install OpenLDAP on FreeBSD, run this command:
sudo pkg install openldap-servers openldap-clients
The OpenLDAP server comes with a default configuration file located at /usr/local/etc/openldap/slapd.conf. Before editing the file, stop the OpenLDAP service with the following command:
sudo service slapd stop
Now, open the configuration file with the nano editor:
sudo nano /usr/local/etc/openldap/slapd.conf
At the top of the file, set the following global parameters:
include /usr/local/etc/openldap/schema/core.schema
include /usr/local/etc/openldap/schema/cosine.schema
include /usr/local/etc/openldap/schema/inetorgperson.schema
These lines enable the three default schema files that come with the OpenLDAP server.
Next, find the access section and set the access control rules based on which LDAP users and groups are allowed access to the server. Here is an example access rule that allows all users to search for information in the LDAP database:
access to *
by * read
You can define LDAP users and groups later in the configuration process.
Now that the basic configuration is set up, create an administrative user named admin with the following command:
sudo slappasswd
This will generate a hashed password that you will use to configure the LDAP root user. Copy the generated hash output.
Open the /usr/local/etc/openldap/slapd.conf configuration file again and find the database section. Add the following lines to define the root user and database:
#######################################################################
# database definitions
#######################################################################
database bdb
suffix "dc=mydomain,dc=com"
rootdn "cn=admin,dc=mydomain,dc=com"
rootpw {SSHA}yourhashedpassword
Make sure to replace yourhashedpassword with the hashed password that was generated in the previous step.
Start the OpenLDAP service with the following command:
sudo service slapd start
To ensure the service starts automatically when the system boots up, run the following command:
sudo sysrc slapd_enable="YES"
Once the OpenLDAP service is running, you can verify that it is working properly by performing a simple search:
sudo ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts
This command should output information about the LDAP naming context.
Congratulations, you have successfully installed OpenLDAP on FreeBSD! You can now start populating the LDAP database with information about network resources such as users, groups, hosts, and services.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
