    If present, specifies that a DCE authorization record be created
    for all accounts in the system authorization file (SYSUAF) that
    do not currently have one. In this case the username and dce-name
    parameters should not be specified as the DCE name is derived
    from the OpenVMS username. Refer to the description of dce-name
    for more details.

    If not present the record to be added is specified by the
    username parameter.
