This doesn't work for me - there is no error, but I get the same result
as above, i.e. the variable ${users} is not set.  Does it work for you?  

What does work for me is using a section property rather than a buffer
property: 

* Dummy Section
  :PROPERTIES:
  :header-args: :R :var user="loris"
  :END:

#+begin_src sh
  echo user: ${user}
#+end_src

#+RESULTS:
: user: loris

However, the restriction to source blocks of a particular language does
not seem to work like this, but maybe I have got the syntax wrong
(again).
