> In method processOneRpc(Bytebuffer buf) in RpcServer.java (branch-1),

> if (!authorizeConnection()) {
> // Throw FatalConnectionException wrapping ACE so client does right thing

> +
> connectionHeader.getServiceName() + " is unauthorized for user: " + ugi);
> }
> {code}
> In method authorizeConnection()
