On CentOS release 5.11 (Final) I created a user and added them to the wheel group with usermod but when I look in the sudoers file at /etc/sudoers the relevant line is commented out.  Looking at groups:[root@arrakis ~]# [root@arrakis ~]# grep wheel /etc/groupwheel:x:10:root,hawat[root@arrakis ~]# [root@arrakis ~]# su hawat[hawat@arrakis root]$ [hawat@arrakis root]$ cd[hawat@arrakis ~]$ [hawat@arrakis ~]$ whoamihawat[hawat@arrakis ~]$ [hawat@arrakis ~]$ sudo echo hello sudo[sudo] password for hawat: hawat is not in the sudoers file.  This incident will be reported.[hawat@arrakis ~]$ and[root@arrakis ~]# [root@arrakis ~]# groups wheel ; getent passwd hawatid: wheel: No such userhawat:x:505:505::/home/hawat:/bin/bash[root@arrakis ~]# Taking a closer look at sudoers:[root@arrakis ~]# [root@arrakis ~]# grep wheel /etc/sudoers## Allows people in group wheel to run all commands# %wheel    ALL=(ALL)   ALL# %wheel    ALL=(ALL)   NOPASSWD: ALL[root@arrakis ~]# I hesitate to uncomment those lines so that the wheel group can run all commands with sudo.  This is an Elastix 2.5 system on CentOS; perhaps there's a reason not to have wheel in the sudo list?Should I just go ahead an manually edit sudoers with visudo?
what are the unforseen consequences to using visudo to enable wheel group to run all sudo commands?
