Authlogic OpenID integration

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 ce开发者_开发问答rtain 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?

i've got the same problem here just now, but fixed just installing the rack-openid gem. I'll ask them to add rack-openid to the required libraries on documentation

I went through the same hassles as you did. Maybe you should just check this out, have got everything working:

http://github.com/shripadk/authlogic_openid_selector_example

This includes a stackoverflow like openid autoregistration too. I have hosted an example app on heroku for you to try out before checkout if you want to.

Not sure how things work on OSX, but in Linux if I install gems as a regular user they get put in my home directory, and if I install them using sudo they go into a system directory.

I've had permissions problems with gems as well, and had to explicitly set a GEM_PATH in my shell to get ruby to load gems from a specific location.

• Do those old gems show up if you run sudo gem list?
• Do you have gems installed in your home directory as well as in /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8?

Edit:

Ok, I'd fire up an irb session and see what happens when you require the gems explicitly.

$ irb
> require 'authlogic'
> require 'authlogic-oid'
...

Edit:

If the authlogic-oid gem is installed, and appears when you run sudo gem list, try starting irb as superuser. If you can then require authlogic-oid, you have a permissions problem: some or all of the gem files are readonly root.

If that doesn't work, you likely have a load path problem - ruby is confused about where to look for your installed gems. In that case, your authlogic gem is probably installed in a different location to your authlogic-oid gem.
