End-user authentication with Azure Data Lake Storage Gen1 using Python

In this article, you learn about how to use the Python SDK to do end-user authentication with Azure Data Lake Storage Gen1. End-user authentication can further be split into two categories:

  • End-user authentication without multi-factor authentication
  • End-user authentication with multi-factor authentication

Both these options are discussed in this article. For service-to-service authentication with Data Lake Storage Gen1 using Python, see Service-to-service authentication with Data Lake Storage Gen1 using Python.

Prerequisites

Install the modules

To work with Data Lake Storage Gen1 using Python, you need to install three modules.

Use the following commands to install the modules.

pip install azure-mgmt-resource
pip install azure-mgmt-datalake-store
pip install azure-datalake-store

Create a new Python application

  1. In the IDE of your choice, create a new Python application, for example, mysample.py.

  2. Add the following snippet to import the required modules

    ## Use this for Azure AD authentication
    from msrestazure.azure_active_directory import AADTokenCredentials
    
    ## Required for Azure Data Lake Storage Gen1 account management
    from azure.mgmt.datalake.store import DataLakeStoreAccountManagementClient
    from azure.mgmt.datalake.store.models import DataLakeStoreAccount
    
    ## Required for Azure Data Lake Storage Gen1 filesystem management
    from azure.datalake.store import core, lib, multithread
    
     # Common Azure imports
     import adal
     from azure.mgmt.resource.resources import ResourceManagementClient
     from azure.mgmt.resource.resources.models import ResourceGroup
    
     ## Use these as needed for your application
     import logging, pprint, uuid, time
    
  3. Save changes to mysample.py.

End-user authentication with multi-factor authentication

For account management

Use the following snippet to authenticate with Microsoft Entra ID for account management operations on a Data Lake Storage Gen1 account. The following snippet can be used to authenticate your application using multi-factor authentication. Provide the values below for an existing Microsoft Entra ID native application.

authority_host_url = "https://login.microsoftonline.com"
tenant = "FILL-IN-HERE"
authority_url = authority_host_url + '/' + tenant
client_id = 'FILL-IN-HERE'
redirect = 'urn:ietf:wg:oauth:2.0:oob'
RESOURCE = 'https://management.core.windows.net/'

context = adal.AuthenticationContext(authority_url)
code = context.acquire_user_code(RESOURCE, client_id)
print(code['message'])
mgmt_token = context.acquire_token_with_device_code(RESOURCE, code, client_id)
armCreds = AADTokenCredentials(mgmt_token, client_id, resource = RESOURCE)

For filesystem operations

Use this to authenticate with Microsoft Entra ID for filesystem operations on a Data Lake Storage Gen1 account. The following snippet can be used to authenticate your application using multi-factor authentication. Provide the values below for an existing Microsoft Entra ID native application.

adlCreds = lib.auth(tenant_id='FILL-IN-HERE', resource = 'https://datalake.azure.net/')

End-user authentication without multi-factor authentication

This is deprecated. For more information, see Azure Authentication using Python SDK.
