NTLM (NT LAN Manager) Authentication is a protocol used by Microsoft to authenticate users and provide secure network communications. NTLM uses a challenge-response mechanism for authentication, where the user credentials are never sent over the network directly. For detailed setup and configuration of NTLM, refer to the official NTLM documentation.
