[Catalyst] Extending C::Plugin::Authentication::Store::DBIC for additional constraints

[Doran L. Barton]

I'd like some advice on how to do this. I'm developing a single Cat app
that will handle multiple sites by looking at the 'host' header. All 
sites will be associated with domain names under a specific domain. Think
wildcard A records in DNS, if you will. For example, all of the following
would be caught and handled by the app:

    foo.mycatalystsite.com
    bar.mycatalystsite.com
    foobar.mycatalystsite.com

I want each site to have its own pool of users for authentication. The
users table, therefore, has a site_id associated with each user. 

Herein lies the gotcha! I need to be able to tell the Authentication plugin
to authenticate the user using $username, $password, and a site_id (as
opposed to the usual $username and $password). After looking through the
Catalyst::Plugin::Authentication::Store::DBIC code, I can't immediately see
how I could subclass it and add this functionality. 

Thoughts, anyone?
