Pass URL Parameters to CRM 7.02 BSP and SSO EP7.3

Hi Portal gurus!

From ECC SAPgui 7.3, we want to pass parameters to CRM web client and not have users entrer  login to CRM web application server.

We have SSO working fine with ECC 6.0 Ehp6 and BW 7.3.1 and CRM 7.02 in EP 7.3.1

Users can login  automtically to CRM from  the portal with Windows AD from IE

We have a url from an ECC ABAP program, it opens a new broswer and user is prompted to logn to CRM web application

http://sapcrmd.insummit.com:8025/sap/crm_logon/default.htm?crm-object-type=BP_ACCOUNT&crm-object-action=B&crm-object-keyname=PARTNER&crm-object-value=

As you can see, this calls the CRM web application server and BSP page directly and not through the portal.  And since CRM is a BSP, there is only a single Iview in the portal, we cannot see how to configure single sign on in this way.

Our enterprise portal is  http://sapportal.insummit.com:50000/irj

We are trying to find the right url string so the request to enterprise portal and passes the parameters on the URL to the CRM BSP BP_ACCOUNT through the portal where we have SSO and SPNEGO working correctly.

Please advise how best accomplish this requirement. 

Sincere Regards,

Lee Lewis
