How to delete Kerberos tickets

[Frank Perry]

Howdy,

I have an app that requests data from a server. I am using Kerberos tickets
for authentication. My problem is that users of remote machines don't log
off those machines and after a number of days, the ticket granting ticket
reaches the end of its renewal period. Under Windows XP sp2 (can't go to sp3
yet), my calls to get a new ticket fail. If I can delete the ticket with
klist.exe, the program will get a new ticket and the user is authenticated.

I am trying to get the function CredDelete to remove the Kerberos ticket so
I can request a new one, but all the calls return that they can't find the
ticket (error 1168). The code looks like

LPCWSTR pwstrPrincipal = (LPCWSTR) "krbtgt/myPlace";
BOOL bCredBack = ::CredDeleteW(pwstrPrincipal,(DWORD) 1,(DWORD)0);

Any ideas what I'm doing wrong?
