Where to specify credential details in Azure Information Protection AzureIP_test sample

I'm trying to get the AzureIP_test sample to work, but am having trouble figuring out where to specify certain credential details.

When I run my version of the sample against a test document, I get the following error:

An unexpected error occurred : Microsoft.InformationProtectionAndControl.InformationProtectionException: The parameter is incorrect. HRESULT: 0x80070057

I suspect I'm missing credential details, but I don't know where to specify the the details in the application.

Specifically, I think I need the following:

SymmetricKeyCredential symmetricKeyCred = new SymmetricKeyCredential(); symmetricKeyCred.AppPrincipalId = ConfigurationManager.AppSettings["AppPrincipalId"]; symmetricKeyCred.Base64Key = ConfigurationManager.AppSettings["Base64Key"]; symmetricKeyCred.BposTenantId = ConfigurationManager.AppSettings["BposTenantId"];

Does anyone know the best place to specify these details? Are there other useful details I'm missing?

you need to provide your AAD Application registration information and how you logon with in the App.Config file that is associated with the sample you are using on GitHub
