{'disabled_groups': [], 'enabled_groups': [], 'enabled_status': 'enabled'}
>>> client.update_passport_config(enabled_status="enabled-for-groups", enabled_groups=["DGC4RP5EMSL1M5EX0321", "DG3MVJRRM9PFDGG3P2CJ"])
''
>>> client.get_passport_config()
{'disabled_groups': [], 'enabled_groups': [{'group_id': 'DGC4RP5EMSL1M5EX0321', 'group_name': 'group_foo'}, {'group_id': 'DG3MVJRRM9PFDGG3P2CJ', 'group_name': 'group_bar'}], 'enabled_status': 'enabled-for-groups'}
