Scope
eduroam CAT is not replacing your helpdesk! While we hope to do you a good service by taking the technical task of generating secure installers for many platforms into our hands, we can not take your users' phone calls or tell them how to fix problems on their computers. The CAT's installers work on the target platforms if these have not been modified beyond reason by the end-user, and we hope the installation process with them is intuitive enough; but we can not give you guarantees that you will not ever hear from failing users again.
