Hi.
We need to use InIFrameRenderingMode for have a possibility to launch reports on OAS 7.6 from Siebel environment.
When SSO is disabled at /em level, in /analytics page we face the issue with the error: "An error occurred during authentication. Try again later or contact your service administrator" at the start page, before login.
This error spoils the impression of the product of OAS, if it is used by thousands of users and each of them, when logging in, will see it.
It would be grate for disappearing this error, like was in previous versions of OBIEE 12c, for example.
