do you speak from s4 or s3? On s4 I've implemented some restriction that 
you can't end without a password on a password set or change.  Code 
taken from "password_hash.c":

If you have the lanman auth mechanism active and you provide only the 
lanman hash you are fine without restriction.

If you face an errorneous behaviour from your point of view then please 
inform us.
