That is what which does.  dpkg -S tells you the package that owns that
file.  In the case of passwd, it is the passwd package.  An apt-cache
show passwd shows the source of that package is shadow.

Title:
  passwd failure resulted in change to unknown password

Status in “shadow” package in Ubuntu:
  Incomplete

Bug description:
  I normally have my user password pretty simple since my computer is
  always under my control. I recently took a trip where I knew it was
  not going to be under my control so I changed it to be more complex,
  using passwd. When I returned from the trip, I tried to change it back
  to the simple one and an error was reported because of the new (?)
  password policy with Natty. So, it looked like it did not change the
  password. However, it did get changed to something which was neither
  the old one or the new one I requested. So I was locked out. I ended
  up having to reinstall. I know this is a tough one because I probably
  won't be able to repeat it, nor do I want to go through the install
  once again. I don't want to give you my password, but I will
  characterize it by saying the simple one was 5 lower case characters
  and 1 number. The complex one was 5 lower case characters and 4
  digits. I tried to change from the complex one back to the simple one
  when the failure occurred.

  Anyway, because of the abnoxious nature of this problem, I wanted to
  report it, even though it may be difficult for you to do anything
  further.
