There is no reason to do this, really. It makes it more difficult to
change the unix (mail) password, and doesn't achieve much. If you want
to prevent windows passwords being sniffed during email, it would be
better to just ssl your mail server.
If you don't do anything, you will get the setup you want, ie different
passwords for samba and traditional unix services. If you want to use
the same password, see pam_smb and auth_smb (squid authentication). Both
can be found on freshmeat.

You need at least:
security = user
(that means samba uses it's smbpasswd file to authenticate users)
domain logons = yes
(causes samba to be a logon server)
encrypt passwords = yes
(windows won't do domain logons with clear-text passwords).
I think that should be it. You will need to enable a netlogon share, yuo
will probably want to make a profiles share, you might want to set login
For each user you want to be able to login to the domain, you need to
create a unix user account, and then run (as root):
# smbpasswd -a <user>

We run about 50 Windows NT/ Windows 2000 clients in a samba-2.2.2 domain
(shortly to be samba-2.2.3).
You might want to take a quick look at
http://mandrakeuser.org/connect/csamba6.html (some hints on joining
machines to the domain), where there is a bit more documentation on
running a domain controller. The samba-howto-collection (in the docs
dir of the samba distribution) is also a good reference, if you haven't
tried it yet.
