Well when you have 2 DC both are authoritative, so if one DC realize
that some attributes in the samdb are not aligned to the value defined
(or implied) by the group policy it fixes them, it looks pretty logical
to me. What is not correct is that if we can fix the password complexity
during provision we should also alter the DC only group policy to have
the same setting here.
