There's more going on the exchange than a simple authentication. The data in the Access-Request packet may have correct data for authentication. The server will correctly authenticate the entity. However server signs the response packet with a different secret than the client making the signature incorrect. The client must check the signature on the Access-Accept packet and if it's not correct must reject the authentication even though the reply type is Access-Accept. DilipSimha.N.M wrote:
hi,
If the shared-secret mismatches bwtween NAS and RADIUS server, then still the access-accept message is sent from RADIUS server to NAS.
why is access-reject message not sent???
