 Using Authentication on a Database Level
 ----------------------------------------
 
 MongoDB supports authentication and authorisation on a database-level. This is mandatory if you have
 e.g. a publicly accessible MongoDB Server. To make use of this feature you need to configure credentials
-for each of your connections. Also every connection needs a database set to authenticate against. The setting is
