  <p>I'm looking for a PHP script or software that would help manage user system access.  For a set of users which I could read from a config file, I could then see for each user, which systems they have access to.  Conversely, for each system or server from a list of servers also read from a config file, I could see which users have access to this server.  </p>
  
  <p>I would then like to be able to add or remove users access to those systems by for instance running a script on those servers or systems.  </p>
  
  <p>Is there anything like this already existing?</p>
