what exactly is the bug in 

(user,callback) => {
  if (user) { callback(null,user) ; }
  return callback( "No user found", null)
  }

?

@isomorphisms I think you want to return; inside the if block as well, otherwise you first run the callback with callback(null, user); and then with callback( "No user found", null);?
