I am using Management ConsoleCE 22.4. Just created a new site-only admin, and assigned admin permissions on that site only. However, after logging in to the new admin, the new admin can view the list of all other admins.
Is it a bug in the Management Console?
No, I was too fast :) Site admins can see the Super Admins, not other site-only admins. So, it’s good enough.
