Developed a targeted feature for the immich-app/immich repository, enabling flexible OIDC session termination through a configurable logout URL override. Focused on enhancing SSO configurability and reliability, the work introduced an option to specify a custom endSessionEndpoint while maintaining default auto-discovery behavior for OIDC logout flows. The implementation involved backend development using TypeScript and JSON, with updates to both tests and documentation to ensure robust session termination across providers. Adjustments to the settings UI improved discoverability and consistency with existing patterns. No bugs were reported, reflecting a well-scoped, quality-driven approach centered on API development and OAuth integration.
