User doesn't get authenticated properly (MongoDB - buildConnectionUrl)

Used MongoDB Version: 3.4 Problem: The user doesn’t get authenticated properly.

File: typeorm/driver/mongodb/MongoDriver.js

MongoDriver.prototype.buildConnectionUrl = function () {
        if (this.options.url)
            return this.options.url;
        return "mongodb://" + (this.options.host || "127.0.0.1") + ":" + (this.options.port || "27017") + "/" + this.options.database;
    };

The created URL seems to be wrong, the correct version should be

(this.options.username != null) ? "mongodb://" + this.options.username + ":" + this.options.password + "@" + (this.options.host || "127.0.0.1") + ":" + (this.options.port || "27017") + "/" + this.options.database : "mongodb://" + this.options.username + ":" + this.options.password + "@" + (this.options.host || "127.0.0.1") + ":" + (this.options.port || "27017") + "/" + this.options.database;

(In case the username is null the “authentication part” in the URL won’t get added)

For me authentication is working with Mongo 3.4, maybe try to add to the options

“authSource”: “admin”

I have checked with a new mongodb instance and a basic example and it worked (using @webstrap’s suggestion) . Please reopen if problem still persists
