    cifs: Call id to SID mapping functions to change owner/group (try #4 repost) · a5ff3769

    Now build security descriptor to change either owner or group at the
    server.  Initially security descriptor was built to change only
    (D)ACL, that functionality has been extended.
    
    When either an Owner or a Group of a file object at the server is changed,
    rest of security descriptor remains same (DACL etc.).
    
    To set security descriptor, it is necessary to open that file
    with permission bits of either WRITE_DAC if DACL is being modified or
    WRITE_OWNER (Take Ownership) if Owner or Group is being changed.
    
    It is the server that decides whether a set security descriptor with
    either owner or group change succeeds or not.
