Use this procedure to configure SSL for AD LDS. This procedure is an example of requesting and installing a server certificate from a Certificate Authority configured on MS Windows 2008.
Be sure that the CA website is configured to use SSL.
If you are running AD LDS on Windows 2012 and use Internet Explorer 10 as the internet browser, you have to add FQDN of your CA to the Compatibility View Settings (Page > Compatibility View Settings). You have to obtain a certificate for the server hosting an AD LDS instance before configuring the instance to use LDAP(s). The certificate must be issued for server authentication.
