I have a PHP site running in IIS and I want to auth my users against my corporate Domain Controller. Running phpinfo() shows my install is using OpenLDAP version 20319. I can auth just fine when I go to the domain controller over ldap://, but if I try ldaps://, it fails.
I read somewhere something about an ldap.conf file, but can't find that on my server. I believe that I need to set up a certificate somewhere and tell php to use that certificate somehow, but I need some help with the details.
