HCI OData Provisioning connecting Backend with SSO

[Former Member]

Hi everyone,

I am trying to configure a destination to my ERP using SAP Single Sign On as authentication on HCI OData Provisioning.

I've already succeeded in configuring the destination to ERP with basic authentication but the documentation to do the same with SSO is not clear.

I am using an HTTP connection to my Back-end ABAP ERP on Cloud Connector.

What i'm trying to accomplish is, that users log into Hana Cloud with their scn accounts and then Hana propagates that credentials to ERP and associates that to a SAP ERP user like in Principal Propagation Authentication.

I tried to configured SAP Single Sign On to achieve this but i am not sure wich steps should i do.

On this screen:

If i want to use SAP ID Service as idp, what should I put in Issuer System ID and Isuer Client? and in Certificate/Singing Key?

Same question to this steps:

Could someone give me some help?

Regards,

Andres

Hello Andres,

please take a look at the Cloud Connector pages for Principal Propagation: SAP HANA Cloud Platform (and sub-chapters). I hope that should answer most of your questions. Let us know, if you still need help with some particular questions.

Hi Ulrich,

Thank you. However, HCI Odata provisioning does not allow the usage of principal propagation (like HCP Destinations does). It only accepts SAP Assertion SSO.

I finally got it working despite HCI Odata Provisioning poor documentation. For the ones that are looking for the same thing:

It doesn't matter what you put in Issuer Client and System ID, as long as you put the same in ACL on ERP, also the certificate and signing key are a self-signed DSA certificate created by you.

1) Certificate
