Error message: {0}

The forest has not been scanned for non-compatible domain controllers. If all the Domain Controllers are not SP1 or above and you enable this feature, there is a possibility that any user can view the password hash for any UNIX user that has been migrated to Windows AD. If this password were to be broken, you would be compromising the Windows password for this UNIX user as well.
Are you sure you still want to enable this feature?
