Issue with BIP security model

Hi,

We are using same BI Publisher instance to integrate with Siebel and BRM. We set BIP security model as “Siebel Security” to make Siebel integration working. But for that Base BRM reports folder is not opening.

When we revert the BIP security model to “Oracle Fusion Middleware” the BRM base reports are working fine.

Can anyone tell me, what is the proper BIP security model to make both Siebel and BRM reports working from single BIP instance?
