My experience with RHEL and CentOS is quite limited, andwould classify me as novice. I have been running CentOS 6for a little over a year and recently brought up a CentOS 7system as a virtual machine under Windows 7. One of the first things I usually do after installation isedit the /etc/sudoers file using visudo to give a specificuser or specific users privileges as indicated in the fileexcerpt below. The visudo editor issued no error messageswhen creating the line for sarah. ## user MACHINE=COMMANDS ## ## The COMMANDS section may have other options added to it. ## ## Allow root to run any commands anywhere root ALL=(ALL) ALL sarah ALL=(ALL) NOPASSWD: ALL On our CentOS 6 systems, the NOPASSWD option works as itis intended to work. No password prompt is presented for commands such as "sudo cat /etc/sudoers". On CentOS 7,the NOPASSWD option does not seem to work, and a promptfor sarah's password is always issued.
Can someone help solve this CentOS 7 mystery? Thank you and best regards.

Wow, regular user getting root without password! This looks scary! Did we have a whole chapter about it in system administration books?
