Rasdan, 
 
Lanun/Iranun/Illanun etc. is a Mindanao tribe. Some of them later settled in North Borneo, Timor and Sulawesi.  
They are the ones that brought the Kampilan to those islands so I think the book is correct on that part (even if they didn't come from Sulu). 
They are famous for their pirating raids, sometimes reaching the Malay Peninsular.
