Step 3: Configure SSL/TLS encryption

Now, we need to configure SSL/TLS encryption for our LDAP server. First, we need to generate a private key and a self-signed SSL/TLS certificate.

Run the following command to generate the private key:

sudo openssl genrsa -out /etc/ssl/private/ldap.key 2048

Next, run the following command to generate the SSL/TLS certificate:

sudo openssl req -new -x509 -nodes -out /etc/ssl/certs/ldap.crt -key /etc/ssl/private/ldap.key -days 3650

During the certificate generation process, you will be prompted to enter some information. Enter the required information and follow the prompts.
