I'd lean towards putting it in the framework.  Then implementation 
issues in underlying auth systems can be resolved independently by 
server / proxy vendors without e.g. requiring changes to the underlying OS.

For instance SSPI which is used for auth on windows servers, only takes 
a single handle to identify the particular conversatioon.  It's finding 
this handle in the absence of any other identifying attribute that I'm 
sure led MS to opt for the connection as the place to store it.  
Probably that plus (in thread per connection model) impersonation
