Worked on the inverse-inc/packetfence repository to enhance authentication workflows with a focus on reliability, security, and observability. Addressed a machine account creation issue by correcting the password hashing sequence, ensuring that passwords are securely hashed only after organizational unit determination. Improved the NTLM authentication API by adding detailed logging, including server name and username context for both successful and failed authentications, and introduced clearer warnings for edge cases such as machine account sharing or incorrect passwords. Utilized Perl and Python for backend development, API enhancements, and troubleshooting, resulting in more robust provisioning and faster root-cause analysis through improved logging visibility.
