If you use BIND DNS for your name resolution (at least with BIND 9 and
greater, although I've been forcibly dragged by the short and curlies
through 4.7+ and 8.1+ and have with relief forgotten them) and use 2
zone A records with the same FQDN, each with a different IP number, an
elementary round robin will be used. Irrespective of what Openldap
provisions there might be :-)))

Best,
