> ClientCnxn.java currently has the following code:
>   if (replyHdr.getXid() == -4) {
>                 // -2 is the xid for AuthPacket
>                 // TODO: process AuthPacket here
>                 if (LOG.isDebugEnabled()) {
>                     LOG.debug("Got auth sessionid:0x"
>                             + Long.toHexString(sessionId));
>                 }
>                 return;
>             }
> Auth failures appear to cause the server to disconnect but the client never gets a proper state change or notification that auth has failed, which makes handling this scenario very difficult as it causes the client to go into a loop of sending bad auth, getting disconnected, trying to reconnect, sending bad auth again, over and over.
