Meteor Users collection usage in Linux/Unix production server

Hey I am trying to deploy my Meteor application on a Linux/Unix production server. I have followed the tutorial -

During development and testing phase I have used in built mongodb. Now during deployment I have to keep separate MongoDB other than the database provided by the meteor as shown below.

dbconnection = new MongoInternals.RemoteCollectionDriver(“mongodb://”);
export const Tasks = new Mongo.Collection(‘tasks’, { _driver: dbconnection });

I can able to access the manually created databases like thins. But my doubt is how can i access the Meteor Users collection which comes along with built in Meteor-Mongodb.
