An administrator set up a new user account called "test". However, the user is unable to change their password. Given the following output: Which of the following is the most likely cause of this…
The correct answer is A. The SUID bit is missing on the /bin/passwd file. Because /bin/passwd isn’t set SUID root (you can see it’s -rwxr-xr-x rather than -rwsr-xr-x), ordinary users lack the privilege to update the shadow file, causing the “authentication token manipulation” error.
