To restrict regions with ESF you have two options:
               	 
            
 
            	 
            
               		
               -  Use the default ES security configuration for the directory server. This ESF configuration and stack of security managers
                  will be applied to each region by default. See 
                  		  Default ES Security Configuration and 
                  		  Add to Default ES Security Manager List for more information.
                  		
               
- Alternatively, you can override the default option on a per region basis. See 
                  		  Server Instance Properties: Security for more information.
