I don't have any groups listed when I create users and can't seem to add users to the Administrative group in the vSphere Client. I can see some of the default users (root, dcui) have the Administrator role, but can't seem to add any new accounts. Grant shell access is enabled as I can definitely log into the host with the new user account.
My environment only has the vSphere Client and the ESXi host; i.e. no vCenter. Would that make a difference in the group/role assignment?
Also, runuser does not exist on the ESXi host either.
