API function

## NAME

shishi\_tkt\_postdated\_p - API function

## SYNOPSIS

**#include \<shishi.h\>**

**int shishi\_tkt\_postdated\_p(Shishi\_tkt \*** *tkt***);**

## ARGUMENTS

- Shishi\_tkt \* tkt

  input variable with ticket info.

## DESCRIPTION

Determine if ticket is postdated.

The POSTDATED flag indicates that a ticket has been postdated. The application server can check the authtime field in the ticket to see when the original authentication occurred. Some services MAY choose to reject postdated tickets, or they may only accept them within a certain period after the original authentication. When the KDC issues a POSTDATED ticket, it will also be marked as INVALID, so that the application client MUST present the ticket to the KDC to be validated before use.

## RETURN VALUE

Returns non-0 iff postdated flag is set in ticket.
