https://localhost/ or to the IP address of your remote server. As Zentyal creates its own self-signed SSL certificate, you will have to accept a security exception on your browser. Log in with the same username for slapd.access4. 1.8. TLS When authenticating to an OpenLDAP server it is best to do so using an encrypted session. This can be accomplished using Transport Layer Security (TLS). Here, we will be our the gnutls-bin and ssl-cert packages: sudo apt install gnutls-bin ssl-cert 2. Create a private key for the Certificate Authority: sudo sh -c "certtool --generate-privkey > /etc/ssl/private/cakey.pem"
