I'm having difficulty getting OpenId authentication working with Authlogic. It appears that the problem arose with changes to the open_id_authentication plugin. From what I've read so far, one needs to switch from using gems to using plugins.

Here's what I done thus far to get Authlogic-OpenID integration working:

1. Removed relevant gems:
   • authlogic
   • authlogic-oid
   • rack-openid
   • ruby-openid *
   • Installed, configured, and started the authlogic sample application (http://github.com/binarylogic/authlogic_example)--works as expected. This required:
   • installing the authlogic (2.1.3) gem ($ sudo gem install authlogic)
   • adding a dependency (config.gem "authlogic") to the environment.rb file.
   • added migration to add open-id support to User model; ran migration; columns added as expected
   • made changes to the UsersController and UserSessionsController to use blocks to save each.
   • made changes to new user-sessions view to support open id (f.text_field :openid_identifier)
   • installed open_id_authentication plugin ($ script/plugin install git://github.com/rails/open_id_authentication.git)
   • installed the authlogic-oid plugin ($ script/plugin install git://github.com/binarylogic/authlogic_openid.git)
   • installed the plugin ($ script/plugin install git://github.com/glebm/ruby-openid.git)
   • restarted mongrel (CTRL-C; $ script/server)

Mogrel failed to start, returning the following error:

I suspect this is related the rack-openid gem, but as it was dependent upon the ruby-openid gem, it was removed when the ruby-openid gem was removed. Perhaps this can be installed as a plugin.

Any assistance with this matter is greatly appreciated--I'm just about to give up on OpenId integration.

* ruby-openid (2.1.2) is installed at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8. I'm not certain if this is affecting anything. In any case, I'm not sure how to uninstall it or if I should.

** edit **

It appears that there are a number of gems in the /Library/Ruby/Gems/1.8/gems directory that may be causing an issue:

• authlogic-oid (1.0.4)
• rack-openid (1.0.3)
• ruby-openid (2.1.7)

Questions: - why doesn't the gem list command list these gems? - Why doesn't the gem uninstall command remove these gems?
