DESCRIPTION:
    This sample demonstrates how to authenticate to the Form Recognizer service.

    There are two supported methods of authentication:
    1) Use a Form Recognizer API key with AzureKeyCredential from azure.core.credentials
    2) Use a token credential from azure-identity to authenticate with Azure Active Directory

    See more details about authentication here:
    https://docs.microsoft.com/azure/cognitive-services/authentication

USAGE:
    python sample_authentication.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Form Recognizer resource.
    2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
    3) AZURE_CLIENT_ID - the client ID of your active directory application.
    4) AZURE_TENANT_ID - the tenant ID of your active directory application.
    5) AZURE_CLIENT_SECRET - the secret of your active directory application.
