While setting up web service for end point integration, we have chosen to do HTTP authentication where we are using a userid and password to configure web service.
I want to know at what level (within on premise solution) this authentication happens. I am sure this authentication will not happen within SAP.
We have following setup from infra point of view:
Ariba P2O > Network Firewall > Proxy > WS > SAP PI > SAP ECC
We are trying to resolve a issue where Ariba is throwing back "Error: Server returned error code = 401" for web services. We are already in touch with Ariba but as we know for on premise network set-up, our infra team should know it.
