Actually I spoke too soon, I do know how to reproduce the
"pre-authentication" error. Simply uncomment the line
"kerbyServer.setInnerKdcImpl(new NettyKdcServerImpl());" in the test. If I
put a printStackTrace in the NettyKdcServerImpl, I see:

Error occured while processing request:Generic error (description in e-text)
