I would expect something like this with PEAP.

ERR: EAP TLS error: -1, 1, 8465,  13062: 1 - error:140940F5:SSL
routines:SSL3_READ_BYTES:unexpected record

Then an Access-Reject is sent back to the client.

The supplicant probably restarts, but that's only because it got an
unexpected response. I most cases I would expect that a midstream EAP
message results as a some sort of error on Radiator side.
