CompTIA Linux+ (XK0-006) — Question 14

Which of the following technologies is used to authenticate users on a Linux server when working in a Windows domain?

Answer options

• A. SSH Daemon
• B. Kerberos
• C. PAM
• D. Samba

Correct answer: B

Explanation

Kerberos is the correct answer because it is specifically designed for secure authentication within Windows domains, allowing Linux servers to authenticate users against Windows credentials. The SSH Daemon is used for secure shell access, PAM is a framework for managing authentication, and Samba facilitates file sharing between Linux and Windows systems, but none of these are primarily responsible for authenticating users in a Windows domain context.
