PROFILE
Lars Delhage
Worked on the SUNET/puppet-sunet repository to enhance security, reliability, and identity management across infrastructure components. Focused on automating the Xrootd TLS and certificate lifecycle, consolidating trust anchors, and upgrading container images to maintain secure communications. Refined authentication and access control by migrating to sunet id authentication and updating permissions for test endpoints. Improved deployment stability through configuration hygiene, enforcing correct file ownership, and resolving Puppet manifest syntax issues. Enhanced mail server and Shibboleth proxy configurations to support multi-subdomain routing and updated trusted proxy IPs. Utilized Puppet, Shell scripting, and configuration management skills to deliver these infrastructure improvements.
