meaningful only for sp side , the implementation of this method will create a local session for the local user identified by the information in the map . the underline mechanism of the session creation and management is application specific . for example , it could be cookie setting or url rewriting , which is expected to be done by the implementation of this method . note that only the first input parameter is mandatory . normally , at least one of the last two parameters should not be null
