Connect remote mongodb with SSL enabled

@robfallows Yes, I checked MongoDB docs, and enabled SSL on MongoDB already. I tested my NodeJS code and verified my Mongodb SSL configuration is correct.

Now I want to connect to Mongodb using a client.pem and ca.pem from my meteor app. I searched a little bit, and found out this ticket What MONGO_URL to connect to MongoDB Server with SSL?

so my question is: to connect to mongodb with SSL, what should I do on Meteor app side, is it sufficient I only do following:
MONGO_URL=mongodb://user:password@ip:port/mydb?ssl=true

How do I tell Meteor where my client.pem and ca.pem are?
