I intentionally created an afs/cell@REALM principal whose kvno does not
exist on the AFS servers.  With 1.5.59 I am unable to reproduce the
problem.  According to the trace output a RXKADUNKNOWNKEY error is
received from the file server.  The STATUS_NO_KERB_KEY is then returned
to the SMB redirector which does not attempt to retry.

Whatever you are experiencing is not obvious.
