Is there a DotNetOpenAuth equivalent that runs on a LAMP stack?

Question

I really love the way the StackExchange family of sites allow someone to log in using their OpenID or OAuth provider, which has been open-sourced as DotNetOpenAuth. This is absolutely wonderful, but I am unable to use it on a *AMP stack.

Is there anything analogous that runs in PHP, Perl, Python or Ruby?

Answer 1

For Perl there's Net::OAuth, and there looks to be an as-yet-unreleased Catalyst::Controller::OAuth, but what the status of that last one is is unknown (other than the OAuth code page says they're "working on" it).

Answer 2

Try Catalyst::Plugin::Authentication::Credential::OpenID - OpenID credential for Catalyst::Auth framework
