Configuration SSO between Business Client and BI 4.0 Explorer

Hi,

I want to get an Information Space (Explorer) out of the SAP Business Client.

We put a URL to an Information Space in the SAP Business Client (ECC) to the BO 4.0 Server.

I configured the default.properties from the Explorer to SAP Authentification.

The manual logon tho the Explorer with SAP authentification works.

SSO didn´t work.

Have somebody information, how to configure the sso?

Regards,

Stefan
