Schema

Microsoft Dataverse supports schema values of 'System' and 'Entities' and can be set using the Schema property.

Using 'System' for Schema property uses the Web API to query entities/tables.

Using 'Entities' for Schema property uses the EntityDefinitions entity set path and retrieves information about EntityMetadata EntityType entities/tables. This will often result in more user friendly names, though requires extra metadata requests.

Connecting to Microsoft Dataverse

To authenticate to the Microsoft Dataverse source, you should first set the OrganizationUrl to the URL of the organization you are connecting to, such as https://[organization].crm.dynamics.com.

Azure AD

Azure AD is a connection type that leverages OAuth to authenticate. OAuth requires the authenticating user to interact with Microsoft Dataverse using an internet browser. The 本製品 facilitates this in several ways as described below. Set your AuthScheme to AzureAD. The rest of the AzureAD flows assume that you have done so.

Desktop Applications

CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See カスタムOAuth アプリケーションの作成 for information about creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId: (custom applications only) Set this to the client Id in your application settings.
• OAuthClientSecret: (custom applications only) Set this to the client secret in your application settings.
• CallbackURL: Set this to the Redirect URL in your application settings.

When you connect the 本製品 opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The 本製品 then completes the OAuth process:

1. Extracts the access token from the callback URL and authenticates requests.
2. Obtains a new access token when the old one expires.
3. Saves OAuth values in OAuthSettingsLocation that persist across connections.

Web Applications

When connecting via a Web application, you need to register a custom OAuth app with Microsoft Dataverse. See カスタムOAuth アプリケーションの作成. You can then use the 本製品 to get and manage the OAuth token values. Get an OAuth Access Token

Set one of the following connection properties groups depending on the authentication type to obtain the OAuthAccessToken:

1. Client Secret
   • OAuthClientId: Set this to the client Id in your app settings.
   • OAuthClientSecret: Set this to the client secret in your app settings.
2. Certificate
   • OAuthClientId: Set this to the client Id in your app settings.
   • OAuthJWTCert: Set this to the JWT Certificate store.
   • OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.

You can then call stored procedures to complete the OAuth exchange:

1. Call the GetOAuthAuthorizationUrl stored procedure. Set the AuthMode input to WEB and set the CallbackURL input to the Redirect URI you specified in your app settings. If necessary, set the Permissions parameter to request custom permissions.

   The stored procedure returns the URL to the OAuth endpoint.

2. Open the URL, log in, and authorize the application. You are redirected back to the callback URL.
3. Call the GetOAuthAccessToken stored procedure. Set the AuthMode input to WEB. Set the Verifier input to the "code" parameter in the query string of the callback URL. If necessary, set the Permissions parameter to request custom permissions.

To connect to data, set the OAuthAccessToken connection property to the access token returned by the stored procedure. When the access token expires after ExpiresIn seconds, call GetOAuthAccessToken again to obtain a new access token.

Headless Machines

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

1. Choose one of these two options:
   • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
   • Option 2: Install the 本製品 on another machine and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.

2. Then configure the 本製品 to automatically refresh the access token from the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

1. Choose one of these options:
   • If you are using the Embedded OAuth Application click Microsoft Dataverse OAuth endpoint to open the endpoint in your browser.
   • If you are using a custom OAuth application, create the Authorization URL by setting the following properties:
     • InitiateOAuth: Set to OFF.
     • OAuthClientId: Set to the client Id assigned when you registered your application.
     • OAuthClientSecret: Set to the client secret assigned when you registered your application.
     Then call the GetOAuthAuthorizationUrl stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.

2. Log in and grant permissions to the 本製品. You are then redirected to the callback URL, which contains the verifier code.
3. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.

Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens. Set the following properties:

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

• InitiateOAuth: Set this to REFRESH.
• OAuthVerifier: Set this to the verifier code.
• OAuthClientId: (custom applications only) Set this to the client Id in your custom OAuth application settings.
• OAuthClientSecret: (custom applications only) Set this to the client secret in the custom OAuth application settings.
• OAuthSettingsLocation: Set this to the location of the file where the driver saves the OAuth token values that persist across connections.

After the OAuth settings file is generated, you need to re-set the following properties to connect:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location grants read and write permissions to the 本製品 to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to create and install a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Once you have successfully tested the connection, copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

• InitiateOAuth: Set this to REFRESH.
• OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
• OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
• OAuthSettingsLocation: Set this to the location of your OAuth settings file. Make sure this location gives read and write permissions to the 本製品 to enable the automatic refreshing of the access token.

Client Credentials

Client credentials refers to a flow in OAuth where there is no direct user authentication taking place. Instead, credentials are created for just the app itself. All tasks taken by the app are done without a default user context. This makes the authentication flow a bit different from standard.

Client OAuth Flow

All permissions related to the client oauth flow require admin consent. This means the app embedded with the CData ADO.NET Provider for Microsoft Dataverse cannot be used in the client oauth flow. You must create your own OAuth app in order to use client credentials. See カスタムOAuth アプリケーションの作成 for more details.

In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions - Delegated and Application permissions. The permissions used during client credential authentication are under Application Permissions. Select the applicable permissions you require for your integration.

You are ready to connect after setting one of the below connection properties groups depending on the authentication type.

1. Client Secret
   • InitiateOAuth: Set this to GETANDREFRESH. You can cuse InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • AzureTenant: Set this to the tenant you wish to connet to.
   • OAuthGrantType: Set this to CLIENT.
   • OAuthClientId: Set this to the Client Id in your app settings.
   • OAuthClientSecret: Set this to the Client Secret in your app settings.
2. Certificate
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • AzureTenant: Set this to the tenant you wish to connect to.
   • OAuthGrantType: Set this to CLIENT.
   • OAuthClientId: Set this to the Client Id in your app settings.
   • OAuthJWTCert: Set this to the JWT Certificate store.
   • OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.

Authentication with client credentials will take place automatically like any other connection, except there will be no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections will take place and be handled internally.

Azure サービスプリンシパル

Azure サービスプリンシパルは、ロールに基づいたアプリケーションベースの認証です。これは、認証がユーザーごとではなく、アプリケーションごとに行われることを意味します。 アプリケーションで実行されるすべてのタスクは、デフォルトユーザーコンテキストなしで、割り当てられたロールに基づいて実行されます。 リソースへのアプリケーションのアクセスは、割り当てられたロールの権限によって制御されます。

Azure サービスプリンシパル認証の設定方法については、カスタムOAuth アプリケーションの作成 を参照してください。

Managed Service Identity (MSI)

Azure VM 上でMicrosoft Dataverse を実行しており、MSI を利用して接続したい場合は、AuthScheme をAzureMSI に設定します。

User-Managed Identities

マネージドID のトークンを取得するには、OAuthClientId プロパティを使用してマネージドID の"client_id" を指定します。

VM に複数のユーザーが割り当てられたマネージドID がある場合は、OAuthClientId も指定する必要があります。
