Ahh good. :)

Looking at the subkey parameter test (previous mail), I
start to suspect, that the authenticator's checksum is
keyed using the subkey or something.
And I further guess, that heimdal (as shishi) just ignores
the subkey for most things.
Which one is "correct according to the specs":
You know the specs better than me.
