I am able to see central user in user management [Uploading: image.png…] is the central user is showing because of the centralUserManagement is configured in 2 node cluster IS and MWS.
If the centralUserManagement is not configured then the central user will not show the user(Cental) in user dropdown list right?
when Central User Management is configured you will only see groups and roles from MWS in IS but not the users themselves.
The groups and roles can than be added to ACLs using the selector dropdown (central instead of local).
