Registering the Azure Active Directory applications and updating the configuration files for this sample using PowerShell scripts

Goal of the scripts

Presentation of the scripts

This sample comes with two PowerShell scripts, which automate the creation of the Azure Active Directory applications, and the configuration of the code for this sample. Once you run them, you will only need to build the solution and you are good to test.

These scripts are:

  • Configure.ps1 which:

    • creates Azure AD applications and their related objects (permissions, dependencies, secrets),
    • changes the configuration files in the C# and JavaScript projects.
    • creates a summary file named createdApps.html in the folder from which you ran the script, and containing, for each Azure AD application it created:
      • the identifier of the application
      • the AppId of the application
      • the url of its registration in the Azure portal.

  • Cleanup.ps1 which cleans-up the Azure AD objects created by Configure.ps1. Note that this script does not revert the changes done in the configuration files, though. You will need to undo the change from source control (from Visual Studio, or from the command line using, for instance, git reset).

Usage pattern for tests and DevOps scenarios

The Configure.ps1 will stop if it tries to create an Azure AD application which already exists in the tenant. For this, if you are using the script to try/test the sample, or in DevOps scenarios, you might want to run Cleanup.ps1 just before Configure.ps1. This is what is shown in the steps below.

How to use the app creation scripts ?

Pre-requisites

To use the app creation scripts:

  1. Open PowerShell (On Windows, press Windows-R and type PowerShell in the search window)

  2. Navigate to the root directory of the project.

  3. Until you change it, the default Execution Policy for scripts is usually Restricted. In order to run the PowerShell script you need to set the Execution Policy to Unrestricted. You can set this just for the current PowerShell process by running the command:

    Set-ExecutionPolicy -Scope Process -ExecutionPolicy Unrestricted

  4. If you have never done it already, in the PowerShell window, install the AzureAD PowerShell modules. For this:

    1. Open PowerShell as admin (On Windows, Search Powershell in the search bar, right click on it and select Run as administrator).
    2. Type: 
      Install-Module AzureAD

  5. Go to the AppCreationScripts sub-folder. From the folder where you cloned the repo,

    cd AppCreationScripts

  6. Run the scripts. See below for the four options to do that.

  7. Open the Visual Studio solution, and in the solution's context menu, choose Set Startup Projects.

  8. select Start for the projects

You're done. this just works!

Four ways to run the script

We advise four ways of running the script:

  • Interactive: you will be prompted for credentials, and the scripts decide in which tenant to create the objects,
  • non-interactive: you will provide crendentials, and the scripts decide in which tenant to create the objects,
  • Interactive in specific tenant: you will be prompted for credentials, and the scripts decide in which tenant to create the objects,
  • non-interactive in specific tenant: you will provide crendentials, and the scripts decide in which tenant to create the objects.

Here are the details on how to do this.

Option 1 (interactive)

  • Just run . .\Configure.ps1, and you will be prompted to sign-in (email address, password, and if needed MFA).
  • The script will be run as the signed-in user and will use the tenant in which the user is defined.

Note that the script will choose the tenant in which to create the applications, based on the user. Also to run the Cleanup.ps1 script, you will need to re-sign-in.

Option 2 (non-interactive)

When you know the indentity and credentials of the user in the name of whom you want to create the applications, you can use the non-interactive approach. It's more adapted to DevOps. Here is an example of script you'd want to run in a PowerShell Window

$secpasswd = ConvertTo-SecureString "[Password here]" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ("[login@tenantName here]", $secpasswd)
. .\Cleanup.ps1 -Credential $mycreds
. .\Configure.ps1 -Credential $mycreds

Of course, in real life, you might already get the password as a SecureString. You might also want to get the password from KeyVault.

Option 3 (Interactive, but create apps in a specified tenant)

if you want to create the apps in a particular tenant, you can use the following option:

  • open the Azure portal
  • Select the Azure Active directory you are interested in (in the combo-box below your name on the top right of the browser window)
  • Find the "Active Directory" object in this tenant
  • Go to Properties and copy the content of the Directory Id property
  • Then use the full syntax to run the scripts:
$tenantId = "yourTenantIdGuid"
. .\Cleanup.ps1 -TenantId $tenantId
. .\Configure.ps1 -TenantId $tenantId

Option 4 (non-interactive, and create apps in a specified tenant)

This option combines option 2 and option 3: it creates the application in a specific tenant. See option 3 for the way to get the tenant Id. Then run:

$secpasswd = ConvertTo-SecureString "[Password here]" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ("[login@tenantName here]", $secpasswd)
$tenantId = "yourTenantIdGuid"
. .\Cleanup.ps1 -Credential $mycreds -TenantId $tenantId
. .\Configure.ps1 -Credential $mycreds -TenantId $tenantId
