(Doc ID 1490768.1)

Last updated on MARCH 08, 2017

Applies to:

Oracle Identity Federation - Version 11.1.1.5.0 and later
Information in this document applies to any platform.

Symptoms

Oracle Identity Federation (OIF) 11.1.1.5 has been installed and configured with Weblogic Server 10.3.5.

OIF has been configured to use Oracle Access Manager (OAM) 11.1.2 (R2) as Authentication Engine. WebGate is installed on the Oracle HTTP Server that is proxying OIF Identity Provider (IdP) requests and the OIF resource /fed/user/authnoam has been protected with OAM. 

When IdP or Service Provider (SP) initiated Single Sign On (SSO) is attempted, the user is redirected to the OAM login page as expected. However after submitting valid OAM credentials HTTP-500 Internal Server Error is displayed.

The OIF TRACE diagnostic log shows that OIF cannot find the Authentication Engine.

Steps to reproduce

1. Configure OIF 11.1.1.5 for integration with OAM 11.1.2 as Authentication Engine.
2. Access an SP resource: the OAM login page in the IdP domain is displayed.
3. Submit valid IdP domain credentials: HTTP-500 Internal Server Error is displayed.
