If I remember correctly I ran into this back in the past - this is a feature in Active Directory. It remembers the old password for some time to allow you to log back in should you mess up your new password. I think there`s some timeout, maybe 5 minutes? after which the old password won`t be usable. If Foreman delegates authentication to Active Directory, this is how it`ll look like. However, since authentication is delegated to Active Directory this cannot be a vulnerability in Foreman. Googled a bit and the timeout is 1 hour.
