OLAP security in Jaspersoft Community Edition ?

Hi,

I'd like to know whether it is possible to apply a security policy on OLAP view in Jaspersoft Community Edition.

In OLAP Workbench, I defined an OLAP schema, plus several roles. The roles are defined in an access grant (.agxml) file. When I define the Mondrian connection in Jaspersoft's portal, there no option to add the access grant file.

Should I include the roles into the XML schema file ?

Any idea ?
