I just posted it for fun. I wasn't looking for a review, though!
The technique is rather complicated, so I'm going to save it for a
longer blog post write up when it's finished.

Agreed. Which is why I posted the feature branch early, to hopefully
convince the ipa community that I'm going about the password stuff the
"right way".

Anyways, back to the question:
What commands can I use to look up the hash, and compute the hash? (Or
simply test if a string password matches the stored password.)

Same questions for the DM password.

Thanks!
