Applies to:

Oracle Access Manager - Version 11.1.1.3.0 to 11.1.2.2.0 [Release 11g]
Information in this document applies to any platform.

Customer has configured EBS R12 (12.1.3) to use Oracle Access Manager 11g (OAM 11.1.1.5) using the osso agent.

Integration between EBS & OAM was done using osso agent <Note:1304550.1> Migrating Oracle Single Sign-On 10gR3 (10.1.4.3) to Oracle Access Manager 11gR1 with Oracle E-Business Suite ...This works fine with form based authentication.
A static page test on a server running a 10g WebGate works with WNA
The issue is that when using OAM WNA and protect the EBS resource to use WNA...this does not work ... getting the homepage it is just blank page with no errors.
The failure is occurring when control passes back to EBS after successful OAM WNA login. The OAM SSO_ID and mod_osso OHS-ID cookies are set. Then the following request is not displaying the EBS Page:

GET /OA_HTML/AppsLogin HTTP/1.1
