> My RSA Windows EAP module sends EAP Notification messages under 4 different error circumstances.   These are typically retry-able input problems. It was the default until the boffins that took over EAP for Windows 7 broke their code.   XP and Vista worked fine, they took the request and responded with a blank response.  No user visible message resulted.  Win7 didn't respond at all, which caused the protocol to break.  They patched it when I pointed out the problem.  But I flipped off the default, don't know if/when that was released.  There is a registry key that controls it.

Interesting. OSX does a similar thing, but it logs the notification, which can be very helpful if you're on the helpdesk and trying to diagnose issues.

I wonder if Windows also does the silent logging.
