During November 2025, Gwilherm worked on the owncloud/ocis repository, focusing on backend development with Go. He addressed a bug in the group creation process by replacing the previously hardcoded 'groupOfNames' LDAP objectClass with a configurable option, allowing deployments to respect the directory schema defined in each environment. This change required careful modification of the graph module to ensure compatibility with diverse LDAP configurations, enhancing both flexibility and maintainability. Although the work was limited to a single bug fix, it demonstrated a thoughtful approach to backend engineering and improved the scalability of group management across different deployment scenarios.
