Hi,
Oh and by broken I mean windows XP type broken, as in will only attempt TLS authentication broken... and sends the username and password a user logged into the machine with by default broken... and so can never work out of the box broken.
FWIW, an unconfigured Windows XP box will not send anything on EAP-TLS for either wired or wireless either - as it needs to have a private certificate or smartcard. both of which are absent. only if you do a quick change of that default entry to make it PEAP will the next broken bits appear (use windows login/password for authentication etc) no. the only sane way is to provide an open wifi connection which is a walled garden under which they can read onfig docs or install a nice configurator program to set their wifi up properly
and were assuming people running linux are clever enough to setup x supplicant without support :)
if they can get their wifi drivers compiled and running, configuring wpa_supplicant is easy! PS dont forget folks that wpa_supplicant also works on the wired interfaces on linux too....so dot1x on wired is 'trivial' with linux alan
