Evaluating open-source IAM frameworks (e.g., Keycloak, FreeIPA) requires a deep dive into protocol support, schema extensibility, and lifecycle management. The objective is to ensure the stack supports robust AuthN/AuthZ and SCIM-based automated provisioning.
Key technical benchmarks include:
- Federation: Support for SAML 2.0, OAuth 2.0, and OpenID Connect.
- MFA Extensibility: Hooks for custom RADIUS or REST-based factors.
- Provisioning: Automated CRUD operations via SCIM or LDAP sync.
- Auditability: Verbose logging to troubleshoot synchronization or authorization failures.
While open-source tools provide a flexible baseline, many enterprises wrap them with managed solutions to ensure high availability and centralized governance.
