Abstract: In an increasingly hybrid IT ecosystem, secure and scalable authentication mechanisms are essential for managing file-sharing services across diverse network environments. Samba, an open-source reimplementation of the SMB/CIFS protocol, enables seamless file and print services for SMB/CIFS clients, most notably Microsoft Windows. While Samba supports several authentication methods, integrating it with the Kerberos authentication protocol significantly strengthens its security posture, especially in enterprise environments. Kerberos, a time-tested network authentication protocol, facilitates secure and mutual authentication without transmitting passwords over the network. This article explores the integration of Samba with Kerberos, focusing on configuration strategies, performance implications, and real-world deployment considerations. It discusses the internal mechanisms of both technologies and illustrates how their integration can simplify centralized identity management using services such as Microsoft Active Directory and MIT Kerberos. Additionally, it reviews security enhancements, troubleshooting practices, and future considerations in the context of Linux-based servers and heterogeneous network environments. By aligning Samba with Kerberos authentication, organizations can achieve a unified and secure authentication architecture that minimizes administrative overhead, strengthens compliance, and provides a resilient foundation for secure file-sharing operations
