OBIEE11g and EBS 12.1.3 Single Sign on same login page.
I am currently integrating the EBS R12.1.3 and OBIEE 11g with OAM11g(11.1.1.5.1). Looking at the doc, configured OBIEE with different Authentication / Authorization Policy than EBS Authentication / Authorization Policy. So two different Sign On pages are being rendered - One from EBSAccessGate for EBS and default OAM Login page for OBIEE.
Reviewing the setup, I think I could set the same EBSAccessGate Login page for both OBIEE / EBS since it is looking for same parameter except OBIEE looking for $user.userid where as EBS looks for that and orclguid. So, question is, is this supported. Has anyone used in the past like this.
