Hi Andrew,

I went back through all the emails that I have seen regarding this case however I don't see any network capture/trace attached. I do have the links to the source code for the client and server. Can you please resend it?

That is the trace already supplied.  (As we fault anyway, just a few
more lines down the gsskrb5_unwrap() processing, , because we don't
match the checksum, even if we match the sequence number)
