If memory serves, SL7 has "Less Brittle Kerberos"[1] where as SL6 does
not. This could account for why one works and the other does not.

Is it possible the two boxes are talking to two different servers?
as the initial post mentioned and showed it was using remote

Oh, I took the question to be about the kerberos server. Yes, you are right,
ntpd -q returns different results on the two machines. However, as I said in
the original post, the time on the two machines is the same to within a very
small amount., well within the five minute tolerance used by kerberos. So I
don't understand why it should matter that the two machines have arrived at the
same time by syncing with different servers.
as a way around, set up ONE unit to act as the local master,
and then sync against it, to get 'site coherent' time
Could you tell me how to do this, or point me at a document that does?
Thanks.

lintes of the following)
