Scenario: custom couple of custom Fiori applications + Fiori Launchpad in HCP up and running.
Currently requires to login using the HCP credentials.
We want to authenticate all users using their backend on-premise ERP credentials (users + passwords managed in SAP ERP - no SSO).
So far I believe in order to do that we need to use an iDentity Provider (iDP) and there are a few options to do that (one of which is using the SAP Portal as iDP). We would like the HCP provided "Cloud Identity" service as the iDP.
In this scenario the end user would access the Fiori Launchpad and will see a login form. Here he/she enters their known SAP backend username/password -> the "Cloud Identity" will verify the credentials with the backend over the trusted connection.
Is there any documentation available specific to this scenario?
How can we do accomplish this?
