How to run this demo:

1.) start the ns

2.) switch properties jacorb.use_domain and jacorb.orb_domain.mount
on and start the domain server

3.) add the following property to enable access control:
org.omg.PortableInterceptor.ORBInitializerClass.sec_init=jacorb.security.level2.ServerInitializer

run the demo.grid server

4.) run demo.ac.DomainSetup to build domain structure and policies

5.) run the grid client to see if it works :-)
