Step 4: Configure LDAP server to use SSL/TLS

Now, we need to configure our LDAP server to use SSL/TLS encryption. Open the LDAP configuration file with the following command:

sudo nano /etc/ldap/ldap.conf

Add the following lines to the end of the file:

TLS_CACERT /etc/ssl/certs/ldap.crt
TLS_REQCERT never

Save and close the file.

Next, open the LDAP server configuration file with the following command:

sudo nano /etc/ldap/slapd.conf

Add the following lines to the end of the file:

TLSCACertificateFile /etc/ssl/certs/ldap.crt
TLSCertificateFile /etc/ssl/certs/ldap.crt
TLSCertificateKeyFile /etc/ssl/private/ldap.key

Save and close the file.
