OpenMRS needs location based restrictions like privilege level access restrictions. So the Location based access control(LBAC) should provide an restriction mechanism to restrict user access only to the logged in location of the authenticated user. That way, if some one is logged in a certain location, they should see only those encounters, observations, and patients registered in that location. But the System Developer account should be able to see patients in all locations.
Initial development of this module was already completed (See here), and now it needs some further improvements as mentioned in the objectives.
