Requirements for executing root level commands by non-root user on Red Hat Enterprise Linux Server.

Issue

• Non-root user is unable to execute root-level commands even after adding the account to sudoers file in /etc/sudoers.d/.

  [root@client ~]# cat /etc/sudoers.d/localuser1
  localuser1   ALL=NOPASSWD:   ALL
  [root@client ~]# su - localuser1
  [localuser1@client ~]$ sudo dmidecode -t1
  [sudo] password for localuser1:  --> Its asking for the password even after adding it to  /etc/sudoers.d/localuser1
