EBS 12.1: Not Able To Log Out In DMZ With Reverse Proxy Configuration (Doc ID 1932750.1)

Last updated on AUGUST 08, 2017

Applies to:

Oracle Applications Technology Stack - Version 12.1.3 and later
Information in this document applies to any platform.

Symptoms

Problem Description

External users are unable to logout as the logout URL is generated incorrectly

See error message in browser "Internet explorer cannot display the webpage"  the url on the page is https://www.ourcompany.com/OA_HTML/OALogout.jsp

When looking at HTTP trace, the actual URL being called at the time of failure is https://extnode.ourcompany.com/OA_HTML/AppsLocalLogin.jsp?cancelUrl=/OA_HTML/AppsLocalLogin.jsp&_logoutRedirect=y&langCode=US

The root cause is due to the hostname in the URL being generated is that of the physical hostname instead of the virtual hostname

Architecture

Are using EBS 12.1.3 and have configured DMZ node following "Oracle E-Business Suite R12 Configuration in a DMZ" <Note 380490.1>

INTNODE - Internal middle tier physical hostname
EXTNODE - External middle tier physical hostname 

myserver.ourcompany.com --virtual host name for internal middle tier 
www.ourcompany.com --virtual hostname for the external (DMZ) middle tier

All internal users using SSO are logging through OAD/OAM and external user are login through the local login.

Profile option "Applications SSO Type" is set to SSWA for node EXTNODE at server level to allow external user access to application directly without SSO.   User identity store for external users are not in OID.

 

 

Changes

 Implemented new DMZ setup
