just a thought (and it may be in the cert documentation for fds)

sometimes you can use subjectAltName to add more names/aliases for the
same system and then there isn't the collision when using the
certificate. I know that the openldap client software is fine with
subjectAltName entries

Lastly, you probably can add to both /etc/ldap.conf
and /etc/openldap/ldap.conf

ssl start_tls

and it should automatically use tls...

ldapsearch -x '(uid=jonesst1)' would be the same as if you added -ZZ
