I thought we had tested DES for pkinit--guess not.

So, if I'm understanding this correctly, unless one of us does
something special,then we will not interoperate for CF2 for DES
enctypes because of this issue, right?  If so, sounds like MIT should
be the one to change because we're the one not following the spec.
