nt password changing now works.

[Luke Kenneth Casson Leighton]

ok.

i got encrypted rpcs in smbd working, tested with "small", i.e only one
dce/rpc fragment.  i've yet to see an encrypted rpc large enough to fit
into more than one dce/rpc fragment.  although, i could set the fragment
size to something bizarre and small.... hm.

ok.  testing against a workstation logged in to a samba domain...
ctrl-alt-del | change password... password change works!  oh yeah!

i tried testing earlier by typing in the domain name, i got a UDP SAMLOGON
query which i had to fix by always putting the unicode data at the end of
the response, but to no avail.  it forces an SMBtrans2 password change
_not_ a \PIPE\samr one.  wierd.  there must be something else in there.

so, to recap, in one sentence: password changing for nt workstations that
are a member of a samba domain now works.
