Enabling SAML V2 redirection to target application

Hi Gurus,

I have been facing to issues for which I cannot find any relevant information. I have been trying to enable SSO SAML 2 on our SAP Netweaver Platform and I am not able to configure everything.

I followed the step by step implementation described here:

http://wiki.scn.sap.com/wiki/display/Security/Single+Sign-On+with+SAML+2.0+and+ABAP+Systems+Supporting+SAP+Logon+Tickets

The only difference lays in the fact that the provider is an external one and not hosted by NW.

The SAML V2 is activated and the SAML backbone  of my customer redirects to the endpoint URL I gave for a test (our java portal address). So this is more or less fine.

But my business case is different as redirecting to a fixed URL: I want to allow any user to run any BEx queries to be authenticated via SAML 2 backbone and to be redirected to the initially targetted query.

Meaning:

A user is accessing the following URL:

http://<server_name>/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?QUERY=<query_id>

The actual situation: the user is getting redirected to the SSO backbone and back to the endpoint I gave meaning:

http://<server_name>/irj/portal

What I would like to have as a behaviour is to:

1- the user request any URL hosted on our Java (it can be BEx query as well as a Web Dynpro application called)

2- he is getting authenticated by the SSO Backbone and redirected to the original URL

I am not an admin and it is hard for me to find the relevant information.

Thanks for helping me!

Cheers,

Cyril.
