List sudo users in centos

Question

How do I list all sudo users at CentOS server?

There are many groups(root, wheel, adm etc) at server, and have users in it. I am looking an easy way/command to find users in all groups who have sudo access.

Note: My user also have sudo access. And I am using 64-bit CentOS release 5.2 (Final).

What have you tried and why didn't it work? It's probably worth noting that "sudo users" isn't all that accurate as the `/etc/sudoers` file can allow certain users or groups to run specific commands as root or some other user but not all commands as all users. — Ladadadada, Jun 03 '13 at 11:16

Try this:

for USER in `cut -d: -f1 /etc/passwd`
do
  sudo -U $USER -l
done

Unfortunately I didn't try this on CentOS, only on Ubuntu. What version of CentOS are you using? – Ladadadada Jun 03 '13 at 11:37
64-bit CentOS release 5.2 (Final). All commands I found over internet are for Ubuntu or other. Those are not working on my CentOS server. – Ahsan Jun 03 '13 at 11:40

It's not a Debian/Ubuntu specific addition. [It's in the source](http://www.sudo.ws/sudo.man.html). You may have better luck with a more recent version of CentOS. – Ladadadada Jun 03 '13 at 11:51
No way on CentOS 5.2 ? – Ahsan Jun 03 '13 at 11:58
@Ahsan You haven't applied updates to your system in FOUR YEARS. It should read CentOS 5.9 today. Go fix that problem :) – Michael Hampton Jun 03 '13 at 16:49
@MichaelHampton I am not in a state to update the System :( – Ahsan Jun 03 '13 at 18:14

What is wrong with sudo cat /etc/sudoers and maybe getent group <groupname> to get usernames of group members?

When adding users with sudo permissions on centos7, its advised to add them to the wheel usergroup which by default has sudo permissions with

sudo gpasswd -a <user_name> wheel

Following @Sven 's answer, does the trick for centos7.

getent group wheel

That may be a good idea, but doesn't answer the question. – RalfFriedl Jan 16 '20 at 10:24
