Hello and thank for your precious time. I try some more tricky password, the problem was there, but not only, I found this post (http://stackoverflow.com/questions/9699912/can-i-change-myself-active-dir...) that to change the password I needed to have ldaps configurated. Configure ldaps solved my problem :) Here is the answer to someone who has my problem.

Can you try some more tricky password, which will pass the policy? For example something like "PaSSword123:{%$#456" instead of just "password" ?
