Azure Databricks & tm1py - ports to open

[eangarit]

Hi,
I have been trying to find this info all over, however no avail.
Question is: When we issue a connection request to authenticate via Cognos Analytics web port 80, do we need the connection to be allow from:
1.- IBM pa App Server ?
2.- Azure Databricks ?

i know we need to open all ports to connect to PA Server instances:ports, however is the authentication through ADMIN server ?

For instance, when I issue a connection such as the following from my Azure Databricks:
namespace = "namespace"
address = "ibmpaAppServer.domain"
gateway = "http://ibmbiGWServer.domain:80/analytics/bi/v1/disp"
port = 8000
ssl = True

pa_session = TM1Service(address=address,
port=port,
namespace=namespace,
gateway=gateway,
ssl=ssl)
is the authentication happening Azure Databricks and/or from server : ibmpaAppServer.domain

As you know this will contribute to setting up the proper firewall rules and avoid opening unnecessary ports.

Thanks for your help,
