[Catalyst] On authentication

[Alex Povolotsky]

Hello!

Comparing tutorial/book and perldoc Catalyst::Plugin::Authentication, 
I've found completely different ways to configure 
authentication/authorization. Looks like Catalyst::Plugin::Authentication
 is much richer, but much worse documented and, say, there is no 
Catalyst::Plugin::Authentication::Store::DBIx::Class mentioned in 
C::P::A manual.

Is tutorial/book way obsoleted? If yes, where can I find better 
explanation of C::P::A?

Alex.
