Have you looked into the -l and -r flags to kinit? -l will allow you
to get tickets longer than the default lifetime, up to a limit of (I
believe) 21 hours. The -r flag allows you to specify the "renewable
lifetime" of tickets, up to a maximum of 1 week. Within the renewable
lifetime, if you have a ticket that's unexpired, you can "kinit -R" to
get a new ticket. "man kinit" for more information on this.
Using this, it's possib le to have your long job running, and also
have a seperate script running with does the equivalent of:
while (1)
kinit -R
aklog
sleep <18 hours>
done
Which should keep you authenticated up to the renewable lifetime
lomit of the tickets.
