We have smartforms calling SAP BAPIs via K2 connect. We would like to use cached credentials available with K2 connect SAP security label as described in http://help.k2.com/en/kb000360.aspx. 

However the KB assumes a custom form where coding is possible, whereas we are using smartforms for which there ins't any coding available. 

Does anyone have any suggestions on how to achieve this?

Thanks.
