If you require a string identifier for your NAS, you can use the 
Client-Shortname attribute in the request list. This just reflects the 
shortname assigned to the NAS using rlm_sql or in client definitions.


if(!"%{NAS-Identifier}"){
	update request {
		NAS-Identifier = "%{client-shortname}"
	}
}
