    Description: Upgradedbformat utility converts old dn format to
    new one.  It's called at the in-place upgrade time.  The utility
    failed to check if the normalized RDN value is in the entry's
    attribute list.  This patch properly checks it.  If the value
    does not exist, it adds the normalized value to the entry.
