我正在尝试使用Python SDK迭代Azure datalake Gen1中的所有文件夹。我正在使用一个服务主体，并为其分配了所有者角色。但是，当我尝试访问某些文件夹时，我得到一个权限拒绝错误。我不确定我是否需要任何其他角色以及，因为业主有最高的特权，我猜。
下面是我正在使用的代码

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

  import re
  import datetime;
  from azure.datalake.store import lib, core
  from azure.common.credentials import ServicePrincipalCredentials
  from pyspark.sql.types import StringType
  from pyspark.sql.functions import udf,split, explode,col,when,concat,array_contains,lit
  import datetime;

  def authenticate(clientId, secretId, tenantId):

      RESOURCE = 'https://datalake.azure.net/'

      tenant = tenantId

      client_id = clientId

      client_secret = secretId

      adlCreds = lib.auth(tenant_id=tenant,

                          client_secret=client_secret,

                          client_id=client_id,

                          resource=RESOURCE)

      adl = core.AzureDLFileSystem(adlCreds, store_name="xxx")

      return adl


  clientId = dbutils.secrets.get(scope = "datalakesecurity", key = "datalakeclientid")

  secretId = dbutils.secrets.get(scope = "datalakesecurity", key = "datalakecredential")

  tenantId = 'xxxxx'

  adl = authenticate(clientId, secretId, tenantId)

  path_to_look= '/'

  level1 = adl.ls(path_to_look)

  print(level1)
