Clusters and security

Existing security configuration of a stand-alone WebSphere Portal is replaced with the security settings of the dmgr cell when it joins that cell. If we remove the node from the dmgr cell, the original security settings are reinstated. Default security is Virtual Member Manager (VMM) federated security with a single file-based repository.

If we configure the security after configuring additional nodes, or if you update the security configuration creating the clustered environment, you will need to run an additional task to update the security settings on the secondary nodess
