I loaded the pcap file into cain but nothing showed up in the MS
Kerberos5 PreAuth section.

Yes, I inspected the pcap file with wireshark and in the AS-REP packet I
see the enc-part rc4-hmac but the actual value is a lot longer than the
sample in mskrb5_fmt_plug.c:24
and I wouldn't know where I can find the 'checksum' value.
