Hi, yes we do have a built-in ADFS task for basic deployment, it’s worth noting that I’m not at all skilled with ADFS, so the script we have is based on user examples. That said, it seems to work well for basic use.
It certainly wise to be cautious and try it out on a test system, but if you review the code you can probably see you should be able to fix anything it does via the normal administrative UI.
You could optionally use a PowerShell scripting task and do the same thing with custom changes:
I can’t advise on Windows Web Application Proxy (which I presume is what you mean by WAP, not a mobile website from 15 years ago!) but if you can find a powershell script that updates the current ssl certificate for that then I could help you adapt that here.
Note that all these examples assume the certificate is already installed into the local machine certificate store under Personal/My, before running the script, which is the default case if you are running this on the same machine that Certify has renewed the certificate on.
