Is the requires-preauth bit set on your krbtgt/MERA.NU principal?  For
reasons I don't personally understand, the "NO PREAUTH" error happens
when a TGS request with no preauth comes in for a service (not client)
principal with requires-preauth set.

Also, although I don't think this is at all relevant, krenew comes from
a different source package from MIT Kerberos, so you might test with
"kinit -R" just to remove that variable.
