Use MongoClient.connect() instead of authenticate() if user provides URI to avoid Db.prototype.authenticate deprecated

Problem

I'm using a connection method like : [code block] ... as indicated in the docs, but receiving the following warning on NodeJS console : [code block] (I get an authentication failure if I omit `?authSource=admin`) Is this normal at this stage (do we need to wait for a next mongoose release ?), or what should I change from now ? Versions : Node : 7.10.0 Mongoose : 4.10.3 MongoDB : 3.4 Thank you.
