3rd party SSL install on Windows server 2012 to enable LDAPS
So I need to install an godaddy SSL cert on my Windows server to enable LDAPS. I was about to purchase the cert when the godaddy rep told me that SSL certs can't be installed on .local domain (mycompany.local) anymore, apparently it was possible years ago.
He told me the work around is to bind teh fqdn to the DC by creating a .local sub domain in a public domain... From what I understood I need to create a .local subdomain in my companies public domain (local.publicdomain.com). I get that part, what I'm confused with is the binding of the DC to the subdomain. Does it mean creating a dns zone for the subdomain and creating a record?
The other solution would've been to have my internal domain with something other than .local but it's a production environment and can't change that.
So can anyone please shed some light on the binding part? Also, I am correct on my assumption of creating a .local sub-domain in my public domain?
Thanks in advanced.
