Setting trusted authentication for BI4.1

Hello Everyone,

I'm configuring SSO using trusted auth between SAP Portal and BO, to recall an Iview ( OpenDocument ) without to be prompted for insert user and pass.

I followed the BI Administration guide applying corrections suggested into SAPNote 2075905, but mechanism still not works!

Is unclear and not properly documented if I have to modify and how, the web.xml under infoview or opendocument folder as I read in some thread.

Any advice is appreciated.

Kind regards,

     Andrea
