We have a Portal customized and integrated to LDAP for SSO.
From the portal, we have a link that takes to another custom application that requires another level of authentication. We have implemented this authentication as custom Database based authentication.
When user login to the portal and access this link, he will be directed for authentication again. This custom application has been installed on a different OC4J instance while Oracle Portal is running in a different OC4J instance.
Issue is though user details are being propagated to the custom application page, we are receiving an error saying authentication failed.
In the OC4J instance specific for this custom application, we have configured jazn.xml to use custom authentication.
