Security Between Narrative Reporting and Essbase Cloud Unexpected Behavior

Summary:

After reading some documentation and asking a related question on Narrative Reporting security, I thought I understood how security would be processed between Narrative Reporting and an Essbase OCI cloud instance, but after reviewing the logs, I'm not sure it is behaving as expected.

Content (please ensure you mask any confidential information):

Here is the scenario.

1. I create a Connection in Narrative Reporting, logged in as a Narrative Reporting Service Administrator. The Narrative Reporting Service Administrator has an identical user in Essbase OCI, but with a different password.
2. In the connection details, I specify the Essbase Administrator details for the connection and test. The connection is successful. This Essbase Administrator does NOT share the same user name or credentials as the Narrative Reporting Service Administrator. and is a separate user altogether from both the Narrative Reporting Service Admin as well as the duplicate Narrative Reporting Service Admin in Essbase. I save the connection.
