What about this:
if there's a non-empty password, present the user with a magic value (8
stars, one star, "[old password]", etc). If the debconf dialog returns the
magic value, keep the password unchanged. If it's anything else (including
an empty value), use whatever is provided.
As long as no one tries to set the password to the magic value, this should
do the trick.
In an unrelated note, I have several users who haven't changed their
passwords after I set it to "Leave it empty". Hey, it was them who said it
should be that way in the first place :p
