Use alfaview on rpm-based Linux (Fedora, Red Hat, CentOs)

Recently, I tried to prepare for an alfaview session. alfaview is a video conferencing system and used by the university where I teach data security. Only earlier this year alfaview introduced Linux support, and only for Debian-based systems. My system is rpm-based (Red Hat Enterprise Linux / Fedora / CentOS), so what to do? A tool like alien did not work for me. Here is what I did to make alfaview run on my rpm-based Linux system.

Some fun digging into IBM Cloud access policies

On IBM Cloud, I have an account with multiple other users. To organize teamwork, I followed best practices for organizing users, teams, applications and made use of the IBM Cloud IAM (Identity and Access Management) capabilities. 

With users, service IDs, access groups, and access policies in place, I wondered how to get insights into per-user privileges and the scope of service ID permissions. Sure, I could use the IBM Cloud console (UI) or the Command Line Interface (CLI), but why not test the API (Application Programming Interface) for some customized reporting? The script is available on GitHub.
