Ok, I have been watching your discourse from afar and I have to say this:

Two things.  Number one, he IS answering your questions.  He is just not GIVING you the answer.  Number two, the gentleman in question is quite possibly the preeminent FreeRADIUS expert in the world.  When he tells you something about FreeRADIUS, you should listen.

Sorry, I am not trying to be too blunt.   But when an expert speaks, you should listen.  This is true in any area.

This kind of Q&A thing helps no one here! Many people are reporting the same issue on different platforms! I don't think the problem is either with the client or the certificates since I conducted some testing using the same client and the same certificates but an old FR version (1.1.7) and the tests pass. It's easier to blame something else but we could spend that time contributing to the solution and so helping others!
