Every time a published dashboard is launched from the Operator Console "view published dashboards" view it requires the user to log in again.
Release : 20.3.x
Component : UIM - OPERATOR CONSOLE
Working As Designed
The cause for this issue has to do with security model changes in OC/CABI, and that the inclusion of the Custom Dashboards from UMP into Operator Console required the use of the "standalone.jsp" version of Dashboard portlet. The standalone version has always required a separate login and there is no way around it.
This cannot be worked around and users will simply have to log in an extra time when viewing these particular dashboards.
