Oracle Reports: REP-56071: "A Security Check Failed With Error Message User Does Not Exist In Id Store" Error When Call Report From Forms After 15 Minutes Idle Time (Doc ID 2776809.1)

Last updated on MAY 01, 2023

Applies to:

Symptoms

On : 12.2.1.4.0 version, SQL*ReportWriter and Oracle Forms

ENVIRONMENT

The environment uses SSO: Forms / Reports 12.2.1.4 + OID + OAM.

OAM is integrated with Forms/Reports using steps from:
  Document:2096585.1 How to Integrate Forms 12c with OAM after a 12c Forms Installation
Specifically, Method: A. Automatically using the Forms Configuration Helper Script

Furthermore, the "Application Domain" that was created by the "Helper Script" is configured in the OAM to use the Kerberos "Authentication Scheme".
WNA uses the login of the Windows terminal to authenticate, that is, when running Forms, it does not need the dialog box with user and password.

(See this link from the OAM documentation for details about Kerberos and WNA.)

PROBLEM DESCRIPTION

Calling Reports from Forms. When spend more than 15 minutes idle in the Form, and then run a report, receive the following message:
 

If refresh the form by refreshing the browser (F5 in IE), then report runs without error. If run the report outside of Forms, then it also works.

The problem happens only after Forms being idle for 15 minutes, even though the error is not a timeout error. Forms timeout is set to 8 hours. 

Changes

 Newly installed/migrated Forms/Reports 12c environment integrated with OAM and OID.
