Samba + Kerberos + LDAP

[Morten S. Laursen]

Hi
For the last couple of days I've been working on getting Kerberos(MIT), 
Samba and LDAP(OpenLdap) working together.
I have no PDC or active directory on site, I wish for the Kerberos/LDAP 
to be the only place where users should be stored (having especially 
passwords in multiple locations seems like to much of a hack).
I need the Samba for file sharing with windows users (primarily Windows 
XP, but there is some Vista installations as well). I managed to connect 
using a Windows machine (XP), but not before I manually added my 
Kerberos server using ksetup.
As I've become a little unsure if I've misunderstood anything, is it at 
all possible to connect to a samba server using MIT kerberos, without 
having to install any extra software or modify any configurations on the 
Windows machines? (quite often we have guests that need to connect, and 
therefore modifying their machines is a no go).
I've tried scanning the network traffic, and the requests from an 
unaltered Windows client newer seem to reach the Kerberos server.
I could really need a clarification on whether what I'm trying to 
accomplish is possible. And if you have any literature  you would 
recommend as well I would appreciate it.

Thank you in advance for any advice
