In this case I think the lifetime of the ticket has to be at least as
long as the runtime of the job, or every mom have to be able to renew
the tickets, which probably complicates things. At least initially.
By, the way, if you have any chance it might be an idea trying to have a
chat with Love Hörnqvist at your central IT Division, Being the main
developers of Heimdal he might have some good ideas and suggestions
about using GSSAPI in Torque.
