Hi Ian,

I have dumped some information on this URL... Can you check this and compare
to your results.

One way to also test your environment is to create password that is longer
then 14 characters (15 will be fine). In this case password can not be
stored as LM "Hash" due to LM design.

Next thing to check would be did your client get new policy. At what level
did you set it? Domain, OU, ... ?

I have few passwords to reset now :-)
