Two Identity Server cluster nodes, running 5.0.0, have been created. When an IdP or SP is created on the first node, the second node does not see the entry until an IdP or SP is added on that node. It then properly displays the correct entries. Clicking on the "list" option to refresh will not show the entries.
The Identity Server nodes are running on RHEL6 with the backend database pointing to Microsoft SQL Server and user repository against Active Directory.
I resolved this by installing the latest service pack from http://wso2.com/products/identity-server/
