Active Directory Federation Services (ADFS) Relying Party Trust Cert Expiry

At work, we received a critical ticket for an application that was unable to authenticate to ADFS. Nothing globally wrong – other applications are authenticating. A long call later, we discovered that the app’s certificate has expired. Why would the application not monitor their certificate expiry dates?? That’s an excellent question, but not one over which I have any control.

can monitor their certs on our side. So I wrote a quick powershell script to grab certificates from the relying party trusts and alerts us if any certs will be expiring in the next 30 days. It has to run on the ADFS server – I’d love to get it moved to the automation server in the future. I expect get-adfsrelyingpartytrust returns disabled agreements. I want to filter out disabled agreements.
