[Geoserver-users] Restricting wfs allowing download of kml files

I followed the boundless tutorial on adding users and restricting access to the geoserver services and data:
http://suite.opengeo.org/opengeo-docs/sysadmin/security/multiuser/index.html

In the scenario of the tutorial only authenticated users can download data. This is ok for me in general but I'd like public users to be able to download kml files. Is that possible?

thank you
