no, to what are known as "trust" accounts. a "workstation" trust account,
for example, allows a user to log in from that workstation. it is used to
encrypt the user's password, for example.

ignoring BDC for now: still if you have:
- no add users from samba but a manual add users system then you're ok. a
pain, but ok.
- a _direct_ change NT / LM password hash, ok
- let's think. a "is_smb_passwd_ok(NThash and/or LMhash)" function:
maybe. yeah, i reckon you could get away with this. we'd have to add it
to the password api...
