Freeradius 3.0.12 - Cisco EAP-Fast Supported?

Hi Alan,

Thank you for your assistance with this!

I worked with my network engineer today and we were able to confirm that PEAP works to authenticate, but when changed over to EAP-FAST, it fails as before.

I have a debug log of PEAP working and then EAP-FAST failing, however, it is pretty dang large at over 4k lines in Notepad++.  I am attaching the text file, with some information changed to protect internal names, MAC addresses, etc.

I am extremely grateful for whatever help you can render me.

Warmest regards,

Kevin Morrison

  It's been tested against other EAP-FAST implementations.

  The full debug may be more useful.

  If the same password works for PEAP (try it), it should also work for EAP-FAST.
