Regarding the password policies in DsfW

The manual states that one should "modify the Domain Password policy to
match his domain requirements" I went and did that, now I have the issue
that I cannot join machines to the domain, because the passwords they use
does not meet complexity requirements.

Can anyone tell me what I should do?

I would like to have the users use (somewhat) complex passwords.
Have computers use whatever passwords are needed to join the domain.
