SSO - SAP Portal and BI 4

Hi,

I have been looking at setting up SSO with SAP BI 4.

I have found that our current SAP systems are accessed via the SAP EP Portal from a drop down menu. There is SAP Logon ticket which is passed to the SAP systems to enable the logon.

Is it possible to setup a SAP Logon ticket which is passed to SAP BI 4.1 to enable SSO? SAP BI 4.1 will be setup to use SAP Authentication with SAP BW.

Thanks,
