Renewal of SAP Passport CA

Background

SAP Business ByDesign uses certificates issued by the SAP Passport Certificate Authority for authentication and encryption

As a part of our commitment to continuous improvement and to deliver industry standards in certificates issued and also with increasing user requirements for supporting higher signature algorithm (SHA256) certificates in our product SAP Business ByDesign, SAP plans to adapt its SAP Cloud Trust Center services including the SAP Passport Certificate Authority (CA) to the latest technology standards. Therefore, the SAP Passport CA certificate and all certificates issued by SAP Business ByDesign using this CA needs to be renewed

SAP will first start to migrate all your test tenants during the regular maintenance window

We emphasis you to take the chance to check after the migration of your test systems what needs to be done from your side and to perform the necessary changes there as well including some smoke test of related functionality. Please inform us in case you encounter problems within your test systems.

After a successful migration of all test tenants, SAP will migrate you productive tenants during the regular maintenance window

Are you affected?

Changes & Impact

Most steps required for the renewal will be taken by SAP for you. However, some steps might need your attention and action. Please find below an overview on how your tenants are affected and if any action is required from your side.

After the renewal managed by SAP, all existing tenant certificates provided and issued by your SAP ByDesign tenant will become invalid immediately and requires you to take an action immediately – please consider the dates provided for test and productive tenants.

All Passport CA certificates used for authentication within inbound communication or email encryption needs to be exchanged latest until November 30th, 2019 as they will not be accepted anymore by the new Passport CA after this date.

The following changes will be done by SAP in your SAP ByDesign tenant:

  • A new SAP Passport CA certificate will be added to the certificate trust list of your SAP ByDesign tenant.
  • SAP generates a new SAP ByDesign tenant certificate that replaces the existing tenant certificate (Also Known as: M-User certificate, client certificate)
  • Certificates used for tenant operations and communication with SAP operational systems (like for example incident processing) will be renewed by SAP.

The following use cases require your action

After SAP has made the central changes as highlighted above, you might need to adjust e.g. communication arrangements, email configuration or other integration configuration. The below use-cases are affected.

You need to take an action when:

  • You have a communication arrangement with an outbound communication with an external system and your communication arrangement uses the authentication method “SSL Client Certificate” with SAP Business ByDesign System Key Pair as certificate
  • You have a communication arrangement providing an inbound communication service for an external system and if it uses the authentication method “SSL Client Certificate”
  • You are using certificate-based e-mail encryption (S/MIME).
  • You are a ByD partner and have an external service or application which has a certificate-based communication with ByDesign
  • You are integrating any third-party application with ByDesign based on SSL Certificate authentication

Detailed description of necessary actions can be found in the following sections.
