    Ticket #47327 - error syncing group if group member user is not synced
    
    Bug description: Windows Sync synchronizes member attributes
    in a group entry if the member entry itself is synchronized.
    The entries in the sync scope are basically to be synchronized.
    But there is an exception such as a container in the scope is
    not synchronized due to the objecttype constraints. Such an
    unsync'ed entry could have users in it. Users are the target
    of Windows Sync.  But since the parent container is not synch-
    ronized, the users in the container are not, neither.  If a
    group contains such special user as a member, synchronization
    failed there and the other normal members are failed to get
    synchronized.
    
    Fix description: Windows Sync has a helper function
    is_subject_of_agreement_remote, which checks if the entry is
    in the scope to be synchronized.  This patch adds the check
    if the checking entry's parent locally exists in the DS. If
    it does not exist, it considers the entry is out of scope.
    AD strictly checks if the entry exists prior to adding it
    to a group entry as a member.  That is, a member to be added
    is supposed to be in the server, as well as its parent is.
    With this change, the AD user which is not synchronized to
    the DS is just skipped to add to the group in the DS in the
    same manner as an user out of scope is.
