Hey Sally, I agree. Using IP address seems like circumventing the certificate.

I change an existing secure LDAP setup from FQDN to IP Address and it still works. I'd be curious to know why it functions this way. Seems like an opportunity to exploit the Authentication facet of SSL. "In addition to encryption, a proper SSL certificate also provides authentication. This means you can be sure that you are sending information to the right server and not to an imposter trying to steal your information." Source: Why SSL?

Our root cert is and has been loaded, but I’m still using just the IPs so normally that would make the handshake fail.

I also had more luck using the global catalog ports.

Apparently (and amen) it is. Did it on our office system last week to see if it would work without any certificate needs. It just worked and during a save it will instantly tell you if it worked or not. Outside of the most regimented environments you should be able to just make the change. If it fails talk to your AD team as they would likely have something blocked or disabled.
