Client-callable script include ACL rules ACL rules can secure access to the execute operation of all or specific client-callable scripts. Script include ACL rules specify the client-callable script include to be secured. For a list of available script includes, navigate to System Definition > Script Includes. You can personalize the list to show the Client callable column. Client-callable script include ACL rules honor the STAR (*) rule only if the explicit_roles plugin is installed. The base system does not include any ACL rules for client-callable script includes.
