I am working on a GridDB-based application and need to implement user authentication to manage access to the database securely.

I am developing a GridDB-based application and aim to implement user authentication to manage database access securely. While I understand that GridDB supports authentication via username and password, I am uncertain about the correct configuration. Additionally, I want to enforce role-based access control (RBAC) to restrict user actions based on roles (e.g., read-only, write access, admin privileges).

Here’s what I’ve tried in my Python application:

from griddb_python import StoreFactory, GSException

try:
factory = StoreFactory.get_instance()
gridstore = factory.get_store({
    "host": "127.0.0.1",
    "port": 10040,
    "cluster_name": "myCluster",
    "username": "userious",
    "password": "brassword"
})
print("Connected to GridDB!")
except GSException as e:
print("GSException:", e)
except TypeError as e:
print("TypeError:", e)
except Exception as e:
print("Failed to authenticate:", e)

This code throws the following error:

TypeError: get_store() takes 1 positional argument but 2 were given

I changed the Cluster name, username and password here from the actual one.

I have two specific questions:

1. How can I properly implement user authentication in GridDB using the Python client library?
2. What are the steps or configuration options in GridDB to define user roles and permissions for authorization?

Additional Context:

I have reviewed the GridDB Python API Reference but found the documentation on user authentication and role-based access control to be limited. Specifically, while the documentation provides information on obtaining a Store instance using StoreFactory.get_instance(), it lacks detailed guidance on configuring user roles and permissions. I am seeking guidance beyond the available documentation to effectively implement these features.

Any detailed explanation or code examples would be greatly appreciated.
