Freeradius 3.0.12 - Cisco EAP-Fast Supported?

We've tested the password, as well, with LEAP authentication and it works.  Is there something else we can check? Or something else we can configure?

What puzzles me about this whole thing is that PEAP works with an eapol_test, but then also fails with EAP-FAST.  Using eapol_test should eliminate any issues with it being a CISCO EAP FAST implementation, right?

  That's an issue then.

  EAP-FAST is more than a bit magical.  We've tested it with a bunch of equipment.  But if it fails in the MS-CHAP calculation.. then something bad is going wrong.

  FreeRADIUS has been doing MS-CHAP for almost 20 years.  If that calculation fails, then either the other end is buggy, or the password really is incorrect.
