Catalyst::Plugin::Authentication::OpenID implements support for OpenID authentication in a Catalyst application. For more information on OpenID, take a look at http://www.openid.net/. In most cases, you'll want to use this plugin in combination with a session plugin for Catalyst. For example, Catalyst::Plugin::Session::FastMmap, which uses a memory-mapped database to store session data. WWW: https://metacpan.org/release/BTROTT/Catalyst-Plugin-Authentication-OpenID-0.02
