Compare AD Properties to SharePoint UPA Properties

Scenario: I had a situation where I had to compare the properties of users from Active Directory to User Profile.

Solution:

1. Export all users from Active Directory to CSV. How?
2. Export all users from User Profile Application to CSV. How?
3. Compare columns between two CSV files using the PowerShell script (ADvsUPAValidation.ps1) below.
