DAViCal Debugging & Authentication Fix

I'm seeking a software engineer with expertise in DAViCal for debugging and updating my existing code. The project involves: - Troubleshooting and resolving authentication issues between a web app server and a customized DAViCal installation. - Fixing integration failures with other authentication systems. Ideal candidates should have a strong background in DAViCal, software engineering, and experience with authentication system integrations. Please note, I primarily need assistance with debugging and updating the old DAViCal code. The DAViCal installation is running on a Linux platform.
