"To: The To header field contains the address of record whose          
registration is to be created, queried, or modified.  The To           header 
field and the Request-URI field typically differ, as           the former 
contains a user name.  This address-of-record MUST           be a SIP URI or 
SIPS URI." 

"From: The From header field contains the address-of-record of the           
person responsible for the registration.  The value is the           same as 
the To header field unless the request is a third-           party 
registration."

" 4. The registrar SHOULD determine if the authenticated user is         
authorized to modify registrations for this address-of-record.         For 
example, a registrar might consult an authorization         database that maps 
user names to a list of addresses-of-record         for which that user has 
authorization to modify bindings.  If         the authenticated user is not 
authorized to modify bindings,         the registrar MUST return a 403 
(Forbidden) and skip the         remaining steps."

My question is the authenticated user in the last paragraph above is
a) extracted from the Request-Uri?
b) the aor in the From header field?
