My reading of the code (I am using a newer version of MIT Kerberos than
you) is that RSA is hard-coded as the signing algorithm. So it looks
like it won't work (I am confident that if I am wrong someone will
correct me). I know that at least at our site we're going to have to
transition to some kind of post-quantum signing algorithm in the future
like many others so I think that eventually this support will be added,
but that doesn't help you now unfortunately.
