LDAP with Azure AD Domain Services

I am trying to connect OpenEMR to an LDAP server supported by Azure AD Domain Services. I setup the LDAP and TLS/SSL certificate following these instructions (Tutorial - Configure LDAPS for Azure Active Directory Domain Services | Microsoft Docs), but I can’t figure out how to load the necessary certificates in OpenEMR to make Secure LDAP work.

The readme is a little unclear to me and I think maybe the certificates are being exported in an incompatible format? https://github.com/openemr/openemr/blob/master/sites/default/documents/certificates/README.md

I see in AuthUtils.php it’s looking for a few certificates/keys to run LDAPS, but I don’t know how to upload them.

Does anyone have experience establishing a Secure LDAP connection?
