Authentication and accessing the request object

[Scott Yeadon]

Hello,
I have set up a basic authetication page using the 
authentication-manager and implementing the Authenticator interface with 
my own class, which works fine. However I need to pass information back 
via the request object within this class but the two parameters for 
Authenticator are of type SourceParameters and HandleConfiguration, 
neither of which provide me access to the request object nor allow me to 
utilise ObjectModelHelper in any way in order to obtain the request 
object. Is the only way I can accomplish this not to use the 
authentication model but instead break it down into separate actions 
which will allow me access to the request? I would rather not do this if 
possible. The relevant areas of my sitemap are shown below.

Thanks.
