Summary
Certificates often get a bad rep, and I believe this is because people think they are a headache to deal with. I see their point. Without knowing how to navigate through the various administrative consoles that deal with your certificate infrastructure, it would be difficult to make even the simplest items function. By talking through the most common certificate-related tasks that any server admin will eventually have to tackle within their own networks, I hope that you have found some comfortability and confidence now to progress with those projects which might be currently sitting on hold, waiting for the certificate infrastructure to be built.
