1 Commits • 1 Features
Apr 1, 2026In April 2026, the team focused on simplifying authentication by transitioning to client ID-based methods. A key feature was delivered for OpenLiberty/open-liberty: User Authentication Simplification via Client ID Methods, removing legacy OIDC provider handling and consolidating authentication hooks to client ID-based methods. The change replaces setThreadOidcProvider/getThreadOidcProvider with setThreadOidcClientId/getThreadOidcClientId, as implemented in PR 34045. This work reduces surface area for misconfiguration, lowers maintenance costs, and strengthens security by eliminating unused OIDC paths. The commit d43d512f15491a2987316428557bcc2fff139553 captures the removal and replacement of methods and ties to PR 34045. These changes lay groundwork for future enhancements to client-ID-based authentication and simplify onboarding for contributors.

Dec 1, 2025December 2025 monthly summary for OpenLiberty/open-liberty: Implemented a critical security and thread-management improvement for EJB invocations. Propagated syncToOSThreadToken from EJBSecurityContext to SecurityCookieImpl and added the token field to SecurityCookieImpl, ensuring the thread identity is reset accurately after each EJB postInvoke. This addresses a gap where the token wasn't carried forward, strengthening security, stability, and predictability of the EJBSecurity flow. Commit bdd9ac2408d65865b57ef063afbcbb2002f740e6 underpins the changes. Business value: reduced risk of cross-request identity leakage, improved thread lifecycle correctness, and smoother downstream security audits. Technologies involved: Java, OpenLiberty EJBSecurity, SecurityCookieImpl, preInvoke/postInvoke lifecycle, code changes for token propagation, regression safety.
