[RADIATOR] What do these error messages indicate ?

[Hugh Irvine]

Hello Neil -

In this case what is usually happening is the target RADIUS server is slow to respond, your RADIUS server sends a retransmission, the first reply comes back from the target which is processed normally, then finally the reply to the retransmission comes back and it is marked as "unknown reply" because the previous reply has already been processed.

The "Bad authenticator" indicates an incorrect shared secret.

regards

Hugh
