I'm using this for reference: https://docs.geoserver.org/stable/en/user/security/layer.html#security-layer
I want to set this layer public, without authentication and available for layer previsualization:
ROLE_ANONYMOUS is a default geoserver role. Also, the WMS service is configured like this:
But I still get this error (from layer previsualization, choosing WMS):
Problem accessing /MySpace/MyLayer/wms. Reason: Full authentication is required to access this resource
Is there something I'm missing?
