During March 2026, contributed to the apache/dubbo-go-pixiu-samples repository by developing a comprehensive SAML authentication sample that integrates Keycloak as the Identity Provider and Pixiu as the Service Provider. This work involved implementing the full SAML authentication flow, including configuration files in YAML, server-side logic in Go, and robust integration tests to validate end-to-end functionality. The sample was refactored into the authentication module to improve maintainability and expanded to support reliable SSO workflows across environments. Efforts also addressed code review feedback, enhanced CI reliability, and provided a reusable, customer-ready solution to accelerate SAML-based SSO adoption.
