I am having trouble understanding how to configure the Wordpress stack to allow secure LDAPS authentication to Active Directory. I have downloaded a couple plugins that enable the functionality of authenticating users via LDAP/LDAPS, but am only able to succeed with the basic LDAP (unencrypted). I need to get the secure LDAP authentication working. My understanding is I need to export the certificate from the domain controller (which I have done) and configure Apache to use this certificate. How do I do that? I see much documentation for setting up SSL connections from the webserver to clients (which I have set up successfully), but nothing for the server to server authentication. Can you assist?
