authDb support

[iMarvinS]

I tried connecting to a db ("called mydB") by using a authDb (called "admin") but I cannot establish a successfull connection.
My connection string is the folllowing one:

mydb_adminuser:asecurepassword@localhost:20900/myDb?authSource=admin

This is the result which is outputed by db ping command:

 { [MongoError: auth failed]
  name: 'MongoError',
  message: 'auth failed',
  ok: 0,
  errmsg: 'auth failed',
  code: 18 }

The authSource parameter is a defined standard in monodb core driver but somehow it doesn´t work in
promised-mongo.
The same connection string (with real credentials) works perfectly in mongoose.

Is there a fix for it? I'm also having this issue
