You are a gentleman and a scholar!  I have made the changes as you suggested for PEAP and tested PEAP-MSCHAPv2.  It works!  I am now able to log the output from ntlm_auth and MS-CHAP-Error.  I'm also excited about the improved TLS logging in 2.1.10.

I will add the code for TTLS now.  Unfortunately, I don't have a way to test that as I don't believe eapol_test supports TTLS and we don't use it.  I suppose someone else can test it once I upload the patch (which I will do after I make the TTLS changes).

Thanks again Alan.
