What you think should happen instead

DefaultAzureCredential authentication method should work as expected using workload identity

How to reproduce

I've created a custom operator to list the filesytem of Azure Data Lake Storage Gen2 using the method "list_file_system" from AzureDataLakeStorageV2Hook class.

class ADLSListFileSystemOperator(BaseOperator):

    template_fields: Sequence[str] = ()
    ui_color = "#901dd2"

    def __init__(
        self,
        *,
        prefix: str | None = None,
        include_metadata: bool = False,
        adls_conn_id: str = "adls_default",
        **kwargs,
    ) -> None:
        super().__init__(**kwargs)
        self.prefix = prefix
        self.include_metadata = include_metadata
        self.adls_conn_id = adls_conn_id

    def execute(self, context: Context) -> list:
        hook = AzureDataLakeStorageV2Hook(adls_conn_id=self.adls_conn_id)
        self.log.info("Getting list of file systems")
        return hook.list_file_system()
