14.2.3.3 New Authentication Method Not Known by Client

Even if client supports external authentication (CLIENT_PLUGIN_AUTH flag is set) the new authentication method indicated in the Authentication Method Switch Request Packet might be not know to it. In that case client simply disconnects.

  1. the client connecting to the server

  2. the server responds with the Initial Handshake Packet

  3. the client sends the Handshake Response Packet

  4. the server responds with the Authentication Method Switch Request Packet to tell the client which authentication method to use.

  5. client discovers that it does not know the authentication method requested by server -- it disconnects.
