[Samba] Samba "unable to validate password" error

I have UNIX accounts and NT accounts.  We do not use the smbpasswd file
because our "password server" in our smb.conf is set to our NT server.
Someone suggested creating an smbpasswd file so I did and put one test
user in it.  It worked but we will only use it as a temporary solution
as we want do not want to manage a separate smbpasswd file.  That's why
we have our NT server as our password server so we can avoid it.  Thanks
for your help.
