Use single-tenant server-to-server authentication - PowerApps

作者:互联网

 

 

 

The single-tenant server-to-server (S2S) scenario typically applies for enterprise organizations that have multiple Microsoft Dataverse environments using Active Directory Federation Services (AD FS) for authentication. However, it can also be applied by environments when the application won't be distributed to other environments.

An enterprise can create a web application or service to connect to any Dataverse environments associated with a single Azure Active Directory (Azure AD) tenant.

Differences from multi-tenant scenario

Creating a web application or service for single-tenant server-to-server authentication is similar to authentication for a multi-tenant organization but there are some important differences.

In the See also section at the end of this article, there are links to information on upgrading a single-tenant application to multi-tenancy.

Requirements

To create and test a single-tenant application that uses server-to-server authentication you will need:

Azure application registration

To create an application registration in Azure AD, follow these steps.

  1. Navigate to https://admin.microsoft.com and sign in, or from your Dataverse environment web page, and select the application launcher in the top left corner.

  2. Choose Admin > Admin centers > Azure Active Directory

  3. From the left panel, choose Azure Active Directory > App registrations (Preview)

  4. Choose + New registration

  5. In the Register an application form provide a name for your app, select Accounts in this organizational directory only, and choose Register. A redirect URI is not needed for this walkthrough and the provided sample code.

    Register an application form.

  6. On the Overview page, select API permissions

    App registration permissions.

  7. Choose + Add a permission

  8. In the Microsoft APIs tab, choose Dynamics CRM

  9. In the Request API permission form, select Delegated permissions, check user_impersonation, and select Add permissions

    Setting API permissions.

  10. On the API permissions page select Grant admin consent for "org-name" and when prompted choose Yes

    Granting API permissions.

  11. Select Overview in the navigation panel, record the Display name, Application ID, and Directory IDvalues of the app registration. You will provide these later in the code sample.

  12. In the navigation panel, select Certificates & secrets

  13. Below Client secrets, choose + New client secret to create a secret

  14. In the form, enter a description and select Add. Record the secret string. You will not be able to view the secret again once you leave the current screen.

Application user creation

You can create an unlicensed "application user" in your environment. This application user will be given access to your environment's data on behalf of the end user who is using your application.

For instructions on creating an application user see Create an application user.

For instructions on managing security roles for an application user see Manage roles for an application user

 Note

In an environment, only one application user for each Azure AD registered application is supported. You will not be able to change the primary email address or username once the application user is created.

When developing a real-world application using S2S, you should use a custom security role which can be stored in a solution and distributed along with your application.

Enable or disable application users

When application users are created, they are automatically activated. In the event that an application user’s status is deactivated and you need to activate it, you do so using the Power Platform Admin Center. You can also use the Power Platform Admin Center to deactivate an application user that is no longer used.

More information: Activate or deactivate an application user

 Caution

Disabling an application user will break all the integration scenarios that use the application user.

Application coding and execution

Follow these steps to download, build, and execute the sample application. The sample calls the Web API to return a list of the top 3 accounts (by name) in the organization.

  1. Download the Visual Studio 2017 SingleTenantS2S sample.
  2. Update the App.config file with your app registration and server key values.
  3. Build and run the application.

Expected results

An OData response listing the names of the top 3 accounts in your organization.

Example console output

Shown below is example console output obtained from an organization that only had two accounts named "Test Account 1", and "Test Account 2".

}
