Port 4244 is specifically used for authentication in which scenario?

Port 4244 is specifically used for authentication when NTLM is applied in a Microsoft Windows environment. NTLM (NT LAN Manager) is a protocol that is employed for authenticating users in Windows-based networks, and it requires the secure handling of credentials. When this authentication method is used, communications are directed through this particular port to ensure that the authentication process is carried out securely within the context of Windows services.

This port serves as an important entry point for the secure exchange of authentication requests and corresponding responses, which is vital in environments where Windows authentication is predominant. By utilizing port 4244, the system can facilitate a seamless and secure authentication process as users access Qlik Sense applications and resources, leveraging the native NTLM protocol efficiently.

The other scenarios described do not involve this specific port mapping for authentication. For instance, client-side HTTP communication and HTTPS for QRS connections pertain to different aspects of communication protocols and do not rely on port 4244 for NTLM authentication. Additionally, handling visual analysis requests does not necessitate the use of this port but rather relies more on the internal Qlik Sense architecture designed for processing such requests.
