Summary

This application demonstrates using the MIP SDK Policy API to list available labels. It prompts the user to input a label, then computes the actions that should be taken. It outputs the metadata that would be applied to the document.

The application demonstrates the following:

  • Initializing the PolicyProfile
  • Adding the PolicyEngine
  • Creating a PolicyEngine::Handler
  • Implementing ExecutionState and providing options to the object to compute actions
  • Looping on ComputeActions(), modifying the execution state with each run to demonstrate desired implementation.

Getting Started

Prerequisites

  • Visual Studio 2015 or later with Visual C++ development features installed
  • Python 2.7 installed and in the system path

Sample Setup

Project folder refers to the MipSdk-PolicyApi-Cpp-Sample-Basic\MipSdk-PolicyApi-Cpp-Sample-Basic directory in the folder where you cloned the repository.

  1. From a command prompt, run: git clone https://github.com/Azure-Samples/MipSdk-PolicyApi-Cpp-Sample-Basic
  2. Launch the project by double-clicking MipSdk-PolicyApi-Cpp-Sample-Basic.sln
  3. When the project starts, set the project type to x64
  4. Right click the project in Visual Studio and select Manage NuGet Packages
  5. Browse for Microsoft.InformationProtection.Policy and install.
  6. In Visual Studio, click the Build menu, then click Build. The application should compile at this point, but will crash if run.
  7. Continue to the steps below to configure the Azure AD App Registration and update the sample code.

Create an Azure AD App Registration

Authentication against the Azure AD tenant requires creating a native application registration. The client ID created in this step is used in a later step to generate an OAuth2 token.

Skip this step if you've already created a registration for previous sample. You may continue to use that client ID.

  1. Go to https://portal.azure.com and log in as a global admin.

    Your tenant may permit standard users to register applications. If you aren't a global admin, you can attempt these steps, but may need to work with a tenant administrator to have an application registered or be granted access to register applications.

  2. Select Azure Active Directory, then App Registrations on the left side menu.
  3. Select New registration
  4. For name, enter MipSdk-Sample-Apps
  5. Under Supported account types set Accounts in this organizational directory only

    Optionally, set this to Accounts in any organizational directory.

  6. Select Register

The Application registration screen should now be displaying your new application.

Add API Permissions

  1. Select API Permissions
  2. Select Add a permission
  3. Select APIs my organization uses
  4. In the search box, type Microsoft Information Protection Sync Service then select the service.
  5. Select Delegated permissions
  6. Check UnifiedPolicy.User.Read then select Add permissions
  7. In the API permissions menu, select Grant admin consent for and confirm.

Set Redirect URI

  1. Select Authentication.
  2. Select Add a platform.
  3. Select Mobile and desktop applications
  4. Select the default native client redirect URI, which should look similar to https://login.microsoftonline.com/common/oauth2/nativeclient.
  5. Under Advanced settings set Treat as a public client to yes.

    This is required only for the MIP SDK sample apps using MSAL for Python.

  6. Select configure and be sure to save and changes if required.

Update Client ID, Username, and Password

  1. Open up main.cpp.
  2. Replace YOUR CLIENT ID HERE with the client ID copied from the AAD App Registration.
  3. Find the tokens for YOUR USERNAME HERE and YOUR PASSWORD HERE and insert test user credentials.

DO NOT hard code a production username and password.

Run the Sample

Press F5 to run the sample. The console application will start and after a brief moment displays the labels available for the user.

  • Copy a label ID to the clipboard.
  • Paste the label in to the input prompt.
  • The applications outputs the metadata associated with the label.

Troubleshooting

If the application fails to authenticate, ensure that python.exe is in the system path and that the version is Python 2.7. Alternatively, updated line 61 in auth.cpp to point to the exact path of the executable.
