Description
After a long delay and false starts, the IceCube Neutrino Observatory has removed GridFTP and x509 certificate authentication. We have migrated to using the Pelican Platform, the Open Science Data Federation, and WLGC Tokens. While this is a common solution, we required several customizations to work with our existing data warehouse structure and make it easier for scientists to use. We wrote a custom WLCG token issuer to support our POSIX filesystem with custom user and group permissions across the entire filesystem. We also made several modifications to HTCondor to ease job submission using tokens, including a custom credmon. After an initially bumpy transition due to several now-resolved Pelican issues. The Pelican-based system has already proven superior to GridFTP in several ways.
