2. Create client application in Azure for the AD Synctool

Follow
Note: The synctool and support is available to our Partners. Are you a New Day at Work Partner and interested? Please contact support@newdayatwork.com

Requirements 
Microsoft SQL Server Compact 4.0
https://www.microsoft.com/en-US/download/details.aspx?id=17876
Microsoft Online Services Sign-In Assistant
https://www.microsoft.com/en-us/download/details.aspx?id=28177
Install PowerShell 5.0 
Install module in PowerShell 5.0:
"install-module Azure"
"install-module AzureRm"
An active Azure subscription is required.

 These are the steps to create the Client App in AAD:

  • Open: "Provision AAD Sync application.ps1" (provided with the synctool) or listed below.
  • Run this script as Admin.
  • Fill in the Admin credentials of the corresponding Office365 tenant.
  • Save and copy all the related information.

 

We recommend to create the required Azure AD application via PowerShell. Therefore PowerShell will create the application and displays the required information.

This script will output you the following info:

  • Tenant ID
  • Tenant Name
  • Client ID
  • ClientSecretKey

You need these value's in the next step. Make sure to save/copy these value's.
