Configuring farm database connections
Note: Use a basic SQL Authentication user
				to configure the connections when creating the farm databases. You cannot use
				Windows authentication. To change the Windows authentication to SQL Server
				Authentication use Microsoft SQL Server Management Studio. Windows Authentication is
				not sufficient for creating farm databases.
			In Microsoft SQL Server, map the user login to these roles of the databases:
db_datareaderdb_datawriterdb_ddladmindb_securityadmin
The same roles apply to these farm databases:
- Config
 - Logs
 - Staging
 - Modeling DB
 - Designer DB
 - Changelog
 - Consolidation journal
