ok, if you support only this and do not support a direct "set NT 16 byte
password hash", then you can't support the "workstation password change
function", which is a workstation trust account set function. this is a

cool! that is actually automatically supported, as it were, in NT SAMs.
but only up to 8 workstations can be put in the list.

all services use nt lm hashes. there actually need (and are) two versions
of this function.
one takes NT hash and LM hash; the other takes an 8 byte challenge plus
the 24 byte NT response (generated by client from 16 byte blah blah) plus
24 byte LM response (generate by client from blah blah) you know the
these two functions already exist therefore in password.c. from what you
