I see the note in DiRT:
NOTE: In 4.1(1) and later, the passwords entered during the password hardening wizard on the new installation (the one you will be restoring over) are used for ALL subscriber templates that are restored. This is to ensure that passwords which may not have been "hard" on the backed up system do not cause failures in the AD/Exchange account creation process during restore.
I just want to clarify with someone who's done this, does this change only the subscriber TEMPLATES as it says, or do subscribers need to be notified that their password will be reset to force them to enter one that meets the new requirements?
Thank you!
