I disable LM hash by default.  I have long SecEdit file that tightens the
whole machine down (too tight sometimes)

My question is this:  when was over 14 characters possible in NT?

I always ran into problems with passwords over 14 characters.  Cannot
remember what the problem was off-hand, I'll have to see if I can
replicate it ....  might have been NT4
