attr_rewrite replaced by ulang

[Gabriel Marais]

Hi Guys

We are in the process of setting up a test environment so we can migrate 
from 2.x to 3.x

Reading the documentation, attr_rewrite is obsolete and should be 
replaced by ulang...


I have this in my sites-available/default

authorized {
	realmchange
	...
}


realmchange is referenced back to:-

         attr_rewrite realmchange {
         attribute = realm
         searchin = packet
         searchfor = ".+"
         replacewith = %{Called-Station-Id}
         maxmatches = 1
         new_attribute = yes
}


1. How do I write this in ulang?
2. Do I put the ulang section under authorize { ... } section?


Many thanks, Gabriel
