Works here. And this way you only have to extract the client key from one of the

Not necessarily. As long as one peer in the trust group has ever synced with
this particular server (has the leapseconds data in memory) and stays up, it
should still provide the leapseconds data to its clients.
Actually my statement was wrong. Putting the leapseconds file on only one peer
didn't work too. It just took longer to produce the same (or similar) errors as
with both peers.
