> mLab itself logs a message about the auth being rejected because the user
> cannot access the "admin" database or somesuch.
> I suggest that if the connection string specifies a database, the drill
> client should forego listing off databases and expose only the database
> provided on the URL.
> Since mLab has a free plan, it shouldn't be too hard to sign up and try this
> out yourself for testing purposes.
