Is there a Samba C/C++ API?

[Mike Papper]

Is there a programming interface to/for Samba? I would like to talk with a NT 
PDC from my C program. If there is no official API + shared object library, 
is there a standard technique for cut-pasting the samba source code and using 
that (or a portion of it) as a shared library - like a do-it-yourself API?

I did see something like this in the mod_ntlm code for Apache. It uses what 
looks like samba API calls to logon a user. I want to do a similar thing (but 
not in Apache) to:

find the following information from an NT Primary Domain Controller:
i) a list of all users
ii) a list of all groups
iii) for a given user, what groups they are in
iv) for a given group, a list of all users

Is this even remotely possible from a C/C++ program (running on linux)?

I hear rumors that "samba doesn't do groups" - is this true? What does it 
mean?

Also, does anyone know of some documentation that ties together windows-based 
authentication - stuff like samba, NT, PDCs, LanMan, LDAP/ActiveDirectory 
etc? 

P.S. could you respond to my email "mike at digitalpipe.net" as I'm not on the 
list yet - and I'm not sure if I should.
