Does AD to Redhat PW sync only apply to those users covered in the sync aGreement?

I am going to set up a one way user sync from the users in one AD OU, and the People container in RHDS. We need to set up passwor dsync, as well. Will the password sync be limited to only those in the sync agreement?

When we create a new user, we create an AD user and and RHDS user. There are already many many AD users already defined in RHDS. When we do our initial sync from AD to RHDS, will new accounts be created in RHDS, or can we populate/create the ntUserDomainID and ntUniqueID attributes in RHDS so that the sync will match the AD user with the existing RHDS user account?

Thanks,
