3634945 - Best Practices for OIDC Client Configuration in SAP SuccessFactors via IAS

When integrating multiple external applications with SAP SuccessFactors through SAP Cloud Identity Services (IAS), customers may have questions about whether to reuse a single OIDC client ID and secret across all applications or configure separate credentials for each.

Not applicable. This is a design and configuration decision rather than an issue caused by a misconfiguration or error.

Recommended Approach: Use Separate OIDC Clients for Each Application

To ensure secure, scalable, and compliant integration, it is recommended to create and manage distinct OIDC client credentials for each application connecting to SAP SuccessFactors via IAS.

Benefits of Using Separate Client IDs and Secrets:

1. Security Isolation:
   - Limits the impact of credential compromise to a single application.
   - Enables application-specific token policies and scopes.

2. Audit and Compliance:
   - Facilitates detailed logging and traceability per application.
   - Supports regulatory and internal audit requirements.

3. Granular Access Control:
   - Allows defining unique scopes and claims per application.
   - Supports least privilege and role-based access principles.

4. Operational Flexibility:
   - Credentials can be rotated or revoked independently.
   - Simplifies troubleshooting and lifecycle management.
