OAM Logout Failing For OAM-Protected Siebel Application Accessed Using IP Address (Doc ID 1097608.1)

Last updated on AUGUST 09, 2018

Applies to:

COREid Access - Version: 10.1.4 and later   [Release: 10g and later ]
Information in this document applies to any platform.


A Siebel application has been protected with Oracle Access Manager (OAM) 10.1.4 in the following architecture:

  • Authenticating OAM WebGate on
  • Siebel Application/Resource OAM WebGate on which can also be accessed using
  • Primary HTTP Cookie Domain = is configured for both Authenticating and Resource WebGates

OAM logout is failing when the Siebel site is accessed using After clicking the Siebel application logout link, if the user re-accesses an OAM protected page in the same browser session there is no prompt to login again.

The problem does not reproduce if the Siebel site is accessed using Fully Qualified Domain Name (FQDN) at

OAM logout from the Siebel application has been implemented by configuring one of the Siebel logout page requests as a LogOutUrl in the Resource WebGate settings. Since the cookie domain is common between the WebGates this usually ensures that OAM logout from both Authenticating and Resource WebGates is effective.

Steps to reproduce

1. User accesses OAM-protected Siebel site in new browser session
2. The OAM form login page is displayed: user submits valid credentials
3. Siebel application pages at are displayed
4. User clicks Siebel site logout link: logout appears to complete successfully
5. In same browser session, user accesses again: the Siebel application page is displayed without prompt to login again
