CompTIA Linux+ XK0-006 (V8) Practice Question

A systems administrator is reviewing the following Pluggable Authentication Modules (PAM) configuration line in the /etc/pam.d/common-auth file:

auth [success=1 default=ignore] pam_unix.so nullok

What is the primary function of the [success=1 default=ignore] portion of this line?

  • It sets a priority level of 1 for the pam_unix.so module and gives it default permissions.

  • If the pam_unix.so module returns a success status, the next module in the auth stack is skipped.

  • The module's result is always ignored, making its execution optional regardless of success or failure.

  • If pam_unix.so fails, authentication for the service terminates immediately and access is denied.
