Need list of users who are having root access

everyone who has the passwort for root has root-access. That's something you can't see on your cluster.

you'll find the other permissions under

isi auth

There are a few ways to look at that question and the obvious one is who has the root password but that not the only way.

• Are there any other accounts with uid=0
• isi_visudo to see who can become root or execute commands as root
• the permissions on any shares where root is allowed
