ticket lifetimes

Actually, looking through the source (src/lib/krb5/krb/get_in_tkt.c and gic_*.c I see that the default client request for ticket lifetime is 10 hours and there is no way to set that in krb5.conf (ok, I haven't looked at the latest release).
So, wrt ticket lifetime you're stuck with 10 hours - or you can change the source.
But you can set the renewable lifetime (and you have to set that in krb5.conf as well as kdc.conf and the principals' records).
