Good morning, all!
I have an ADFS installation I inherited. I just updated the SSL certificate for ADFS, and I wanted to install the ADFS Toolbox to the server so I can run health checks and intercept any issues before they get to be emergencies.
However, when I try to install via the Powershell Gallery or via manual installation, PowerShell won't find the module. I used this resource to get the manual toolbox.
Any thoughts on what I'm missing?
Thanks to all for looking!
