We are using SH Clustering with Eneterprise SEcurity with F5 Load balancer. We have a requirement from our SOC team to display the dashboard on the TV - 24/7 so that they can monitor it continuously. Our users are connected through LDAP. I am aware off the setting - ui_inactivity_timeout in web.conf to zero so that it will never expires.
If you want to create a non-LDAP user, then you can do this in a Cluster. If you follow these instructions, then it will get replicated across the Cluster:
Another option is to embed the Report or Dashboard within another site.
