In the blog How to Connect Your Cloud Applications with Your Corporate User Store you have seen, how to connect cloud applications with your Microsoft active directory corporate user store. In this blog we will showcase how you can leverage your existing NW Identity Management as a User Store to access your Cloud applications in HCP. By using the existing NW Identity Management you would not require another user store in the cloud but just plug in your existing User Store with the SAP Identity Service.

Prerequisites:-

  • You have an SAP HANA Cloud Platform account.
  • You have requested your SAP Cloud Identity service tenant(SCI).
  • You have requested this feature from an SAP Cloud Identity service operator by creating a ticket on SAP Support Portal under the component BC-IAM-IDS.
  • Note: On SAP HANA Cloud Platform, your consumer account should be subscribed to a proxyapplication provided by an sci account.
  • NW AS JAVA system 720 and above with IDMFEDERATION<release>.sca installed .For more details click here

Configure NW AS JAVA identity management:

  1. The on premise system is an AS Java with a deployed SCA from SAP Single Sign-On (SSO) 2.0. For the configuration of the on-premise AS Java system, proceed as follows,Open the Identity management in your netweaver Java system and create a scimuser with the SCIM_READONLY role assigned.

Configure SAP Cloud Identity Service:

  1. If you have the SAP Cloud Identity service tenant activate first, then open the admin console [https://<scitenanthost>/admin].Now click on tenant settings tile –>Go to Tenant SAML2.0 configuration–>download the metadata file and keep it, because it is required to configure custom IDP in consumer account[HCP tenant].
  2. Now activate the corporate user store in your SCI tenant because by default it will be disabled. Go to the URL [https://<scitenanthost>/admin/ #togglz] and activate the corporate user store based on your requirement[productive or testing]This provides the option to configure the proxy application.

Note:The configuration for test mode in the SAP Cloud Identity Administration Console will not be available for customers (when you use the togglz option).
