    Description

      The 'admin', 'local' and 'config' databases are special databases within the system. Users can not create them. However, it is possible for a user to create them with an alternative casing because these checks on _configsvrCreateDatabase will not match the alternative casings.. This can lead to those databases being incorrectly added to 'config.databases'.
