I really hate to be daft here, but I am still not understanding
something:

I want samba to accept the password that is supplied as part of the
connection from windows,  when it does this, it should check against my
password server (the domain controller) instead of the smbpasswd file,
can someone point me in the right direction.  I agree with the one
respondent that said that from a security standpoint it is very bad
practice to have each user give me their network password to enter into
the smbpasswd file, but I haven't been able to get samba to authenticate
against the domain, instead of the smbpasswd, so right now that's the
only recourse I have
