💖 shishi_tkt_may_postdate_p(3) 💖

okay bestie, welcome to the shishi manual, section 3 — and today's main character is shishi_tkt_may_postdate_p, an API function that checks one very specific little flag for you. no cap. let's get into it ✨

✨ NAME ✨

shishi_tkt_may_postdate_p — it's an API function, bestie. that's the whole vibe.

🌸 SYNOPSIS 🌸

#include <shishi.h>

int shishi_tkt_may_postdate_p(Shishi_tkt * tkt);

🎀 ARGUMENTS 🎀

  • Shishi_tkt * tkt — your input variable, holding the ticket info. that's it. she's the only one here. 💅

🦋 DESCRIPTION 🦋

so what does she actually do? she determines if the ticket may be used to grant postdated tickets. periodt.

now here's the lore, because this flag is lowkey misunderstood:

the MAY-POSTDATE flag in a ticket is normally only interpreted by the ticket-granting service. it can be ignored by application servers — like, they just don't care, it's not their business, they're giving main character energy elsewhere. 🙈

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. (yes, that's ALLOW- and POSTDATE with a line break in the original, but it's one option name, iykyk.)

this flag does not allow a client to obtain a postdated ticket-granting ticket. postdated ticket-granting tickets can only be obtained by requesting the postdating in the KRB_AS_REQ message. so like… don't try it, bestie, that's not what this is for. 💀

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. and the KDC MAY limit how far in the future a ticket may be postdated. so there are limits, and the KDC is the one holding the clipboard. 👑

🔥 RETURN VALUE 🔥

returns non-0 iff the may-postdate flag is set in the ticket. so: truthy = yes she may, falsy = nope. 🫶
