we have two seperate nodes called Roles and Permission. Roles contains set of
permissions.
How we can define relationship between Roles and permissions? 
In case if delete permissions than Role must be deleted. 
I referred openLDAP document but no more information. I heard about "alias".
will that help for referential integrity?
