Establishing a Connection
Creating a JDBC Data Source
You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Microsoft Planner consists of three basic steps:
- Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
- Provide the driver class. For example:
cdata.jdbc.microsoftplanner.MicrosoftPlannerDriver
- Provide the JDBC URL. For example:
jdbc:microsoftplanner:InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333; or jdbc:cdata:microsoftplanner:InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;
You can use the second format above whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:microsoftplanner:" or "jdbc:cdata:microsoftplanner:" and can include any of the connection properties in name-value pairs separated with semicolons.
Connecting to Microsoft Planner
Entra ID (Azure AD)
Note: Microsoft has rebranded Azure AD as Entra ID. In topics that require the user to interact with the Entra ID Admin site, we use the same names Microsoft does. However, there are still CData connection properties whose names or values reference "Azure AD".
Microsoft Entra ID is a multi-tenant, cloud-based identity and access management platform. It supports OAuth-based authentication flows that enable the driver to access Microsoft Planner endpoints securely.
Authentication to Entra ID via a web application always requires that you first create and register a custom OAuth application. This enables your application to define its own redirect URI, manage credential scope, and comply with organization-specific security policies.
For full instructions on how to create and register a custom OAuth application, see Creating an Entra ID (Azure AD) Application.
After setting AuthScheme to AzureAD, the steps to authenticate vary, depending on the environment. For details on how to connect from desktop applications, web-based workflows, or headless systems, see the following sections.
Desktop Applications
You can authenticate from a desktop application using either the driver's embedded OAuth application or a custom OAuth application registered in Microsoft Entra ID.
Option 1: Use the Embedded OAuth Application
This is a pre-registered application, included with the driver. It simplifies setup and eliminates the need to register your own credentials and is ideal for development environments, single-user tools, or any setup where quick and easy authentication is preferred.
Set the following connection properties:
- AuthScheme: AzureAD
- InitiateOAuth:
- GETANDREFRESH – Use for the initial login. Launches the login page and saves tokens.
- REFRESH – Use this setting when you have already obtained valid access and refresh tokens. Reuses stored tokens without prompting the user again.
When you connect, the driver opens the Microsoft Entra sign-in page in your default browser. After signing in and granting access, the driver retrieves the access and refresh tokens and saves them to the path specified by OAuthSettingsLocation.
Option 2: Use a Custom OAuth Application
If your organization requires more control, such as managing security policies, redirect URIs, or application branding, you can instead register a custom OAuth application in Microsoft Entra ID and provide its values during connection.
During registration, record the following values:
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was that was generated when you registered your custom OAuth application.
- CallbackURL: A redirect URI you defined during application registration.
For full instructions on how to register a custom OAuth application and configure redirect URIs, see Creating an Entra ID (Azure AD) Application.
Set the following connection properties:
- AuthScheme: AzureAD
- InitiateOAuth:
- GETANDREFRESH – Use for the initial login. Launches the login page and saves tokens.
- REFRESH – Use this setting when you have already obtained valid access and refresh tokens. Reuses stored tokens without prompting the user again.
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- CallbackURL: A redirect URI you defined during application registration.
After authentication, tokens are saved to OAuthSettingsLocation. These values persist across sessions and are used to automatically refresh the access token when it expires, so you don't need to log in again on future connections.
Web Applications
To authenticate from a web application, you must register a custom OAuth application in Microsoft Entra ID (formerly Azure Active Directory). Embedded OAuth apps are not supported in this context because web-based flows require a registered redirect URI and centralized credential management.
This approach is designed for hosted, multi-user environments where access must be delegated through a secure, standards-compliant OAuth workflow. It gives your organization control over the OAuth client, redirect URI, branding, and permissions scope.
Before you begin: Register a custom OAuth application in the Azure portal. During registration, collect the following values:
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- CallbackURL: A redirect URI you defined during application registration.
For full instructions on how to register a custom OAuth application and configure redirect URIs, see Creating an Entra ID (Azure AD) Application.
To authenticate using AzureAD in a web application, configure the following connection properties:
- AuthScheme: AzureAD
- InitiateOAuth: OFF – Disables automatic login prompts.
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- CallbackURL: A redirect URI you defined during application registration.
Because web applications typically manage OAuth flows manually on the server-side, InitiateOAuth must be set to OFF. This allows you to explicitly control when and how tokens are retrieved and exchanged using stored procedures.
After configuring these properties, follow the steps below to obtain and exchange OAuth tokens:
- Call the GetOAuthAuthorizationURL stored procedure:
- CallbackURL: Set to your registered redirect URI
- Open the returned URL in a browser. Sign in with a Microsoft Entra ID account and grant access.
- After signing in, you are redirected to your CallbackURL with a code parameter in the query string.
- Extract the code and pass it to the GetOAuthAccessToken stored procedure:
- AuthMode: WEB
- Verifier: The authorization code from the CallbackURL
- The procedure returns:
- OAuthAccessToken: Used for authentication.
- OAuthRefreshToken: Used to refresh the access token.
- ExpiresIn: The lifetime of the access token in seconds.
To enable automatic token refresh, configure the following connection properties:
- InitiateOAuth: REFRESH
- OAuthRefreshToken: Your previously obtained refresh token
When InitiateOAuth is set to REFRESH, the driver uses the provided refresh token to request a new access token automatically.
After a successful connection, the driver saves the updated access and refresh tokens to the file specified by OAuthSettingsLocation.
You only need to repeat the full OAuth authorization flow if the refresh token expires, is revoked, or becomes invalid.
For more background on OAuth flows in Microsoft Entra ID, see Microsoft Entra Authentication Overview.
Headless Machines
Headless environments like CI/CD pipelines, background services, or server-based integrations do not have an interactive browser. To authenticate using AzureAD, you must complete the OAuth flow on a separate device with a browser and transfer the authentication result to the headless system.
Setup options:
- Obtain and exchange a verifier code
- Use another device to sign in and retrieve a verifier code, which the headless system uses to request tokens.
- Transfer an OAuth settings file
- Authenticate on another device, then copy the stored token file to the headless environment.
Using a Verifier Code
- On a device with a browser:
- If using a custom OAuth app, set the following properties:
- InitiateOAuth: OFF
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- Call the GetOAuthAuthorizationURL stored procedure to generate a sign-in URL.
- Open the returned URL in a browser. Sign in and grant grant permissions to the driver. You are redirected to the callback URL, which contains the verifier code.
- After signing in, save the value of the code parameter from the redirect URL. You will use this later to set the OAuthVerifier connection property.
- If using a custom OAuth app, set the following properties:
- On the headless machine:
- Set the following properties:
- AuthScheme: AzureAD
- InitiateOAuth: REFRESH
- OAuthVerifier: The verifier code you saved.
- OAuthSettingsLocation: The path of the file that holds the OAuth token values.
- For custom applications:
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- After tokens are saved, reuse them by setting:
- InitiateOAuth: REFRESH
- OAuthSettingsLocation: Make sure this location grants read and write permissions to the driver to enable the automatic refreshing of the access token.
- For custom applications:
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
- Set the following properties:
Transferring OAuth Settings
- On a device with a browser:
- Connect using the instructions in the Desktop Applications section.
- After connecting, tokens are saved to the file path in OAuthSettingsLocation. The default filename is OAuthSettings.txt.
- On the headless machine:
- Copy the OAuth settings file to the machine.
- Set the following properties:
- AuthScheme: AzureAD
- InitiateOAuth: REFRESH
- OAuthSettingsLocation: Make sure this location grants read and write permissions to the driver to enable the automatic refreshing of the access token.
- For custom applications:
- OAuthClientId: The client Id that was generated when you registered your custom OAuth application.
- OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
After setup, the driver uses the stored tokens to refresh the access token automatically, no browser or manual login is required.
Azure Service Principal
The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow. It does not involve direct user authentication. Instead, credentials are created for just the application itself. All tasks taken by the application are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.
Create an AzureAD App and an Azure Service Principal
When authenticating using an Azure Service Principal, you must create and register an Azure AD application with an Azure AD tenant. See Creating an Entra ID (Azure AD) Application 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 permissions and Application permissions. The permissions used during client credential authentication are under Application Permissions.
Assign a role to the application
To access resources in your subscription, you must assign a role to the application.
- Open the Subscriptions page by searching and selecting the Subscriptions service from the search bar.
- Select the subscription to assign the application to.
- Open the Access control (IAM) and select Add > Add role assignment to open the Add role assignment page.
- Select Owner as the role to assign to your created Azure AD app.
Client Secret
Set these connection properties:
- AuthScheme: AzureServicePrincipal to use a client secret.
- InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- AzureTenant: The tenant you want to connect to.
- OAuthClientId: The client Id in your application settings.
- OAuthClientSecret: The client secret in your application settings.
Certificate
Set these connection properties:
- AuthScheme: AzureServicePrincipalCert to use a certificate.
- InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- AzureTenant: The tenant you want to connect to.
- OAuthJWTCert: The JWT Certificate store.
- OAuthJWTCertType: The type of the certificate store specified by OAuthJWTCert.
You are now ready to connect. Authentication with client credentials takes place automatically like any other connection, except there is no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections take place and are handled internally.
Managed Service Identity (MSI)
If you are running Microsoft Planner on an Azure VM and want to automatically obtain Managed Service Identity (MSI) credentials to connect, set AuthScheme to AzureMSI.
User-Managed Identities
To obtain a token for a managed identity, use the OAuthClientId property to specify the managed identity's client_id.If your VM has multiple user-assigned managed identities, you must also specify OAuthClientId.
