I'm adding Kerberos V4 authentication to a client/server application, and am
having a problem with expired service tickets. The client properly
requests and gets a service ticket the first time with krb_mk_req. But once
the service ticket expires, it stays in the cache; subsequent calls to
krb_mk_req don't fetch a new ticket. So how do I either delete the expired
ticket, or force krb_mk_req to fetch a new service ticket no matter what?
I've thought of using get_ap_tkt, but it appears to be purely for Kerberos'
internal use, and hence may not be portable to V5 or other future versions.
Also, are there any books which discuss Kerberos programming in detail and
would cover this sort of thing?
Thanks in advance...
