This object is used by the manager to create
or delete the row entry in the ccsUserDbTable
following the RowStatus textual convention.
This row can be deleted regardless of the
value of ccsUserDbState. If all ccsUserDbTable
rows have been deleted, then other mechanisms,
such as intercepting RADIUS flows, may be used to
associate a user name with an IP address. If
this is not possible, then the user name will
be absent from generated accounting records.
