How to Set up a kdc kerberos server on vista business edition

hello ,

I have a vista business edition ACER machine.

I am trying to setup kerberos so that I can use it for authentication
in my JEE (java) application that is running on Glassfish. In my case
I will have both the Kerberos client and server on the same machine
since I am mainly trying to set up a demo and don't have access to two
machines. After figuring out the JAAS infrastructure for Kerberos I
thought I had it solved and then realized that I had no KDC Kerberos
server.

I have downloaded the kerberos client from MIT. That was fairly easy
to set up.

But I cannot seem to find a good explanation (not too complicated) of
how to set up the KDC Kerberos server on my vista machine. I have
found on google comments stating that Active Directory is the way to
go. But then when I search for info on Active Directory I get lost in
the complexity. I usually am able to figure things out by brute force,
read as many search hits as possible regarding a problem and finally
the answer will come. But in this case brute force has not worked.
Even some search hits that said it is not possible to setup kerberos
on vista.

Is there anyone here who can help me ie. point me in the right
direction or give me some hints. My background is mainly in
programming (jee java in this case) and application servers
(Glassfish). I am certainly not a seasoned windows admin.

It would be very nice to know how to set up a secure password system
using Kerberos in java using Glassfish.

Many hanks for any help.
