Is it possible to override authorative reverse DNS lookups?

Question

Hello,
I am part of collaborative workgroup which has a group of networked computers that are installed at each others sites. This means that often a server has two names - a "site name", which is the name in DNS, such as BigFoot.yale.edu at X.X.X.5 and a "workgroup name", the name used by the group for distributed processes, such as YaleBigFoot.workgroup.net also at X.X.X.5 in our /etc/hosts file.
We are trying to use globus and GSI authentication in between the servers which requires valid reverse dns lookups, such that a CN=host/ .
On unix'y servers, this requires setting up a rather comples /etc/hosts and editing /etc/nsswitch so that /etc/hosts is used authoritively for all lookups.
I have been trying to replicate this behavior for our Mac users, and I'm running into problems. I have read all the "reverse dns" documentation I can - and it appears that my problem is different.
I have setup a /etc/hosts file and a /etc/lookupd/hosts configuration file and a /etc/named.conf section for workgroup.net and a /var/named/workgroup.net.zone file.
However I still get the following output:
$ host yale-bigfoot.workgroup.net
yale-bigfoot.workgroup.net has address X.X.X.5
$ host X.X.X.5
X.X.X.5.in-addr.arpa domain name pointer workgroup-router-node.net.yale.edu.
Is it possible to override the authorative reverse lookups?
Thank you in advance,
Brendan

However, you can achieve do something that looks similar to overriding.
class Parent {
  Parent(int i, String s) {
    // do stuff
class Child extends Parent {
  Child(int i, String s) {
    super(i, s);
    // do Child stuff here
new Parent(1, "abc");
new Child(2, "xyz");Although that's not overriding, it sort of looks similar. Is this what you were talking about?
