[Catalyst] Newbie question

[Ivan Wills]

Hi,

I am trying to create a new Catalyst application that requires that I 
use a lot of old code that is based on the DBI. The first thing that I 
am trying to do is work out how to use the catalyst authentication 
system with users that I already have code for password checking etc.

I guess that I need to sub class some modules of 
Catalyst::Plugin::Authentication but I am not sure which I need to do 
that to or really what the difference between Store and Credential is 
(what is store storing?). Do I need to create a Model that relates to 
the store?

I have read the tutorials, manual and Catalyst::Plugin::Authentication 
and related modules documentation but I still cannot get my head arround 
how it should work.

Any pointers on how to go about doing this would be appreciated.

Thanks
Ivan Wills
