Hmm, firstly: You need to work in HEAD here, no further development
will occour in 2.2 and you will just confuse me - I have already changed
this stuff around a fair bit.
You also probably missed the 'change_lanman_password' at the bottom on
api_SetUserPassword. It doesn't get the plaintext, but does change the
LM hash. (but not the NT hash)

Starting to. We need one of two things:
a 'user password change' fucntion, that takes the old password, new
password, a flags feild and returns an NTSTATUS. The flags should
indicate if the old password is actually there, and if the new password
is plaintext or an LM hash.
It should probably do some of the things that are done in
pdb_set_plaintext_password(), but I'm not quite sure.
It should certainly enforce a 'minimum password length' paramater, and
possibly check with cracklib (if so configured)
or a 'user password change authorization' fuction - but getting this all
in one place would be good.
