AS-REQ with till being the epoch

[Weijun Wang]

It looks like if I set the till field in AS-REQ to the epoch, the issued ticket will have a very big endtime (Ex: now it's 2106-02-07 06:28:15 (UTC)).

Well, this is OK.

But if I call kvno with this TGT in ccache, I see a "Ticket expired while getting credentials" error. Maybe somewhere in the KDC that very big endtime is mistakenly treated as a very small number?

My KDC is compiled from the head of https://github.com/krb5/krb5.git/.
