Don't know about slurpd replication at all yet, have still to learn that part of openldap. However, regarding DNS, you won't get a lot of "chatter" if you run a caching DNS server on the machine running slurpd. It will cost you virtually no performance loss whatsoever. Putting an entry in /etc/hosts might work instead, as long as the resolver has been told to look up hosts before dns. > 2.

Either kill and restart the caching nameserver, or change the entry in /etc/hosts. In the latter case, the effect will be immediate, since it's the resolver which looks this up, not slurpd. Do 'ldd /usr/local/libexec/slurpd' (if that's where it is) to confirm this, look for "libresolv".
