What are postdatable tickets?

Normally, a ticket is valid starting from the time you request it until it expires. However, there may be some cases where a user would like a ticket that is valid some time in the future. For example, a user may wish to run a batch job next week, but your maximum ticket lifetime is only one day. To accommodate this need, Kerberos 5 introduced postdatable tickets. These are tickets which are initially invalid, and have a starting time some time in the future. To use a postdatable ticket, the user must send it back to the KDC to have it validated during the ticket’s valid lifetime.
