You need to set up their certificate so they understand all their names
in (to the best of my knowledge) their one certificate.

If you are using a single instance of slapd (not running a slapd for
each fqdn with different ports for each one), then I believe you are
limited to a single certificate. I have not found any globally
recognized certificate makers who will make you a certificate that will
keep the subjectAltName values. You would need to have a DNS:fqdn entry
for each of the hostnames (beyond the primary name of the machine) that
clients will use to contact your server.

I think it is not possible to do that. I believe (and if I'm wrong, I
hope someone will correct me) that you either have to generate a
certificate using subjectAltName keyword listing fqdn's 2 through n or
you need to run multiple instances of slapd each with its own config
file (thus able to have its own certificate/key) and not able to share
