# shishi\_tkt\_may\_postdate\_p(3)

API function

## NAME

shishi\_tkt\_may\_postdate\_p - API function

## SYNOPSIS

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

**int shishi\_tkt\_may\_postdate\_p(Shishi\_tkt \*** *tkt***);**

## ARGUMENTS

- Shishi\_tkt \* tkt

  input variable with ticket info.

## DESCRIPTION

Determine if ticket may be used to grant postdated tickets.

The MAY-POSTDATE flag in a ticket is normally only interpreted by the ticket-granting service. It can be ignored by application servers.  This flag MUST be set in a ticket-granting ticket in order to issue a postdated ticket based on the presented ticket. It is reset by default; it MAY be requested by a client by setting the ALLOW- POSTDATE option in the KRB\_AS\_REQ message.  This flag does not allow a client to obtain a postdated ticket-granting ticket; postdated ticket-granting tickets can only by obtained by requesting the postdating in the KRB\_AS\_REQ message. The life (endtime-starttime) of a postdated ticket will be the remaining life of the ticket-granting ticket at the time of the request, unless the RENEWABLE option is also set, in which case it can be the full life (endtime-starttime) of the ticket-granting ticket. The KDC MAY limit how far in the future a ticket may be postdated.

## RETURN VALUE

Returns non-0 iff may-postdate flag is set in ticket.
