The problem here is that you are mixing up an expired password and an
account that is locked out.
An account can get logged out for various reasons, but the main one is
something trying to auth with an old or wrong password. Do you have
anything that tries to authenticate to AD with the username and
password, if so, check it is using the right password, mobile phones
are a favourite place to start.
