I just setup a new server with a minimal installation of AlmaLinux 8. AlmaLinux is a variant of free Red Hat Enterprise Linux 8. It’s like a CentOS 8, but will have a full support until the end of RHEL 8 life cycle. This server is to serve as a new proxy for all VMs inside my home lab. I want to use tinyproxy which is need to be compiled from source as the RPM package is not available as of the time writing....

So how do we find out if the Kerberos (principal) ticket expires programmatically?...

Fortunately, someone has posted a solution as the following: Credit: update to Centos 7; libpcre.so.0 No such file or directory
