title: azure-sdk-python status code not found GraphRbacManagementClient
body: <p>I am trying to enumerate Azure AD users from an azure subscription, with this code:
  WORKING_DIRECTORY = os.getcwd()
      TENANT_ID = "REDACTED_AZURE_ID_OF_MY_AZURE_AD_USER"
      AZURE_AUTH_LOCATION = os.path.join(WORKING_DIRECTORY, "mycredentials.json") # from: az ad sp create-for-rbac --sdk-auth > mycredentials.json</p>
  
  <pre><code># I've tried with get_client_from_cli_profile() while logged in azure CLI
  # I've tried with and without parameters auth_path and tenant_id
  rbac_client = get_client_from_auth_file(GraphRbacManagementClient,auth_path=AZURE_AUTH_LOCATION, tenant_id=TENANT_ID)
  
  # Try to list users
  for user in rbac_client.users.list():
      pprint(user.__dict__)
  </code></pre>
  
  <p>As I've detailed in the comments, I've tried to fix the issue with a couple of unsuccessful attempts, here is the stacktrace</p>
