Well, at this point looking from

Tue Nov 22 14:26:21 2011 {MYRADIUS_IP}:61645 TLS Auth Error: Auth
Username/Password verification failed for peer

the best guess I can give you is incorrrect user/pass. Why? Well, to
answer that we need to look at FR debug log. Which you didn't send.
Without that, your guess is as good as mine.

It works. I know, I tried it :)

My guess is it's related to PAM. IIRC if the user doesn't exists in
the system (i.e. /etc/passwd), pam will send garbage password to
radius. Which is why I suggest using radiusplugin directly.

And again, if you have FR-related problems, run it in debug mode and
post the log here.
