NTLM and SMB go opt-in
Summary
Daniel Stenberg explains why NTLM and SMB are being moved to opt-in in curl, highlighting security flaws, backward-compatibility issues with HTTP/2/3, and the plan to disable by default in curl 8.20.0. SMBv1 and NTLM are discouraged due to weak cryptography and practical limitations, with a roadmap toward eventual removal. This update is important for IT teams relying on curl-based automation and legacy integrations.
