NAME

       shishi_tkt_invalid_p - API function

SYNOPSIS

       #include <shishi.h>

       int shishi_tkt_invalid_p(Shishi_tkt * tkt);

ARGUMENTS

       Shishi_tkt * tkt
                   input variable with ticket info.

DESCRIPTION

       Determine if ticket is invalid.

       The  INVALID  flag indicates that a ticket is invalid. Application servers MUST reject tickets which have
       this flag set. A postdated ticket will be issued in this form. Invalid tickets MUST be validated  by  the
       KDC  before  use,  by presenting them to the KDC in a TGS request with the VALIDATE option specified. The
       KDC will only validate tickets after their starttime has passed.  The  validation  is  required  so  that
       postdated  tickets  which  have  been  stolen  before their starttime can be rendered permanently invalid
       (through a hot-list mechanism).

RETURN VALUE

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