Thanks to everyone that replied, you have helped me understand what 
direction I should be going (or staying away from).  Here are the highlights 
and my comments to some of the suggestions that were provided, since I can't 
respond to every thread from the digest.  The opinions both for and against 
OpenLDAP have made me take a little closer look at it, but my conclusion is 
that it is more cumbersome than what I really want to handle right now for 
the size of the network.  I have looked closer at Samba/Wins/Winbind, etc. 
and it looks like the main source of my current problem is that my Samba 
network is setup now as a Workgroup and not as a Domain.  I didn't 
understand that difference when I ran across the quote I included above.  It 
looks like if I change to a Domain and configure it properly with 
Wins/Winbind that I should be able to have the single point password 
changing option occur from the Windows desktop.  I am now re-reading 
sections of my copy of the Definitive Guide to Samba 3 which should help me 
(although it was published before Vista and 7, which all my workstations are 
now).

Also thanks to some for the suggestions of using ClearOS or Webmin.  I do 
have Webmin installed and use it for some of my administrative functions. 
So if I do try playing around with OpenLDAP I will certainly see if it will 
reduce my learning curve on getting it setup properly.  With the new gateway 
box that I mentioned above, I have been planning on installing ClearOS on 
it, so I will take a look at how it might be used to learn about using LDAP. 
Although I was thinking to have this box function more strictly as a gateway 
than providing services to the internal lan.

Jeff
