{quote}Not understand why you add your own which i don't think necessary,
better you can explain more.

Perhaps you're right... it may not necessary to be honest. My reasoning was
just that handling it before the SASL logic seemed less complicated. Rather
than jumping around all those conditionals in the RpcServer SASL code, I can
just handle it before even going in -- as I have the authcode at that point in
the execution.
I do see your point, however. It should make the netty client changes a lot
more straightforward too. I'll move some things around and use those functions
we have already. Thanks for the review!
