Not quite;

If you pass the 14 character margin, No LM hash will be stored of the
password. 14 characters is its limit, so if you enforce a policy of 15 or
greater you do not have to worry about it.

That's only correct if you're using LM and/or haven't made the registry 
change to get rid of the backwards compatibility mode.  NTLM and NTLMv2 do 
not suffer from this problem.
