@zippydan I don’t think you understand how Radius works. The exchange with radius is done between the “authenticator” and the Radius server. The Authenticator in your setup is OpenVPN. Pfsense’ Radius setup knows nothing about how/what data is passed between Radius and OpeVPN - Nor does it know anything about what encryption it might have.
So what you are asking would require pfSense’s “test authentication” module to have a full authenticator featureset. Not a simple task, and certainly a lot of code for no real benefit. But it would be nice if it at least had a PAP/Chap/Chapv2 selectorbox for the test as the last two are standard hashmodules where all the code is readily available and would be easy to implement.
