Kunio Namba enhanced the glpi-project/glpi repository by implementing secure database connection support for MySQLi during the installation process. He focused on security hardening by enabling SSL for database connections, ensuring that sensitive data remains encrypted in transit. Kunio refactored the installation flow to use mysqli->real_connect instead of mysqli->connect, allowing SSL options to be properly applied whenever SSL is enabled. This work required careful integration of PHP and database management skills, as well as command line interface expertise. The update addressed a specific need for encrypted connections, demonstrating a focused and technically sound approach within a short development period.
