Oracle Portal Login With Oracle SSO - OAM Integration Fails With 'Internet Explorer cannot display the webpage.' (Doc ID 1195323.1)

Last updated on MARCH 08, 2017

Applies to:

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

Symptoms


Oracle Single Sign-On (OSSO) 10.1.4 has been integrated with Oracle Access Manager (OAM) 10.1.4.x. Access and login to OIDDAS pages using the OAM login page is successful. However login to Oracle Portal with OSSO-OAM integration is failing.

In Internet Explorer (IE) browser only, when the Login link is clicked from the Portal home page the following error is displayed:


Internet Explorer cannot display the webpage.



Using Firefox browser the error does not occur: the OAM login form is successfully displayed and after submitting valid credentials the user is redirected back to an authenticated Portal session.


Symptoms

The IE browser HTTP Header trace shows that when the Oracle SSO login request is received, the SSO (resource) WebGate returns HTTP-302 Redirect response to redirect the user to the Authenticating WebGate for login. Internet Explorer is generating 'cannot display the webpage' error immediately when it receives that HTTP-302 response having Location: http://OAM_authn_WebgGate_hostname.domain:port/obrareq.cgi?........

For example:


....
GET /portal/pls/portal/PRT_PORTAL.wwsec_app_priv.login?p_requested_url=http%3A%2F%2Fportal.oracle.com%3A7778%2Fportal%2Fpage%2Fportal%2FDesign_Time_PG%2FWelcome&p_cancel_url=http%3A%2F%2Fportal.oracle.com%3A7778%2Fportal%2Fpls%2Fportal%2FPRT_PORTAL.home HTTP/1.1
  Host: portal.oracle.com:7778

HTTP/1.1 302 Redirect to Oracle SSO Server for login
