Explanation:
* The following components need to be installed:
.Net 4.5.1
PowerShell (PS3 or better is required)
* Azure AD Sync requires a SQL Server database to store identity data. By default a SQL Express
LocalDB (a light version of SQL Server Express) is installed and the service account for the service is
created on the local machine.
SQL Server Express has a 10GB size limit that enables you to manage approximately 100.000 objects.
This is fine for the scenario in this question.
If you need to manager a higher volume of directory objects, you need to point the installation
process to a different version of SQL Server.
AAD Sync supports all flavors of Microsoft SQL Server from SQL Server 2008 to SQL Server 2014.
