In SQL Server 2012, there is a new feature called "contained databases" - I've blogged about it here and here. With this feature comes a new layer of security that may creep onto your radar if you use this functionality: contained user authentication failures. There are a variety of things that can go wrong here. If you connect with a contained user but forget to specify a database name, SQL Server will attempt to authorize you as a SQL login, and you will
