CAC/PKI - Client Cert Auth

Product: PowerShell Universal
Version: 2.10.2

Wanted to check here and see if anyone has experience with CAC/Smart Card Auth with Universal. I’m new to this and struggling to understand how the process works. I’ve been able to get the IIS Server to accept Certs but im getting a 403 Forbidden error from Universal once the authenitication takes place.

My organizations uses a one to many type PKI setup so I’m assuming I need Universal to check the actual CA trust but I have no clue how to do any of that at this point.

Any and all help would be much appreciated.
