[Samba] password sync unix

(I'm sorry for my previous message with the wrong
subject; I'll just do it over again)
I have a Solaris 10 machine (SunOS 5.10
Generic_118833-18 sun4u sparc)
installed with Samba Version 3.0.23a.
Samba has been compiled from source with PAM modules. 
The modules 'pam_smbpass.so' and 'pam_winbind.so'
reside at: /usr/local/samba/lib/security
smb.conf is located at /usr/local/samba/lib/

We are talking about /etc/pam.conf, not /etc/pam.d/
configuration with separate files.
The modules for pam.conf are in /usr/lib/security/$ISA

This is what I want: 
Users have a unix shell and use a tool that exports
the output to an CSV file on the samba share. 
I'm forced to use password expiration. I would like
the users to change their password only once. 
Either by syncing the /etc/password or /etc/shadow
file with the smbpassword file, or by just validating
the samba login against the /etc/password or
/etc/shadow file. I don't really care, as long as it

I've been searching documentation, mail list archives,
How-to's and man pages, I've tried with trial and
error. I raised the debug levels for smbd and nmbd and
checked the log files for hints, including the system
log files. 

I just cannot get it to work. The smbpasswd file
remains unchanged after a password change. Am I just
not understanding the concept here, or is there a
simple thing I've forgotten or overlooking??

What is the service name for samba to be used in
pam.conf?? I assumed (and read here and there) it is
'samba'. But is it really?? 
PAM describes the service name should stated in the
man page of the service. This is not the case with
smnd or nmbd (at least, I can't find it). 

Below are some summaries from both pam.conf and
smb.conf. Just the things I think that are related.
But if someone need the whole thing, please let me

Is there anyone who can help me?? I really need to
get it working one way or another. 

Many thanks for your effort. It's much appreciated!
