Redmine

I'm trying to "Allow OpenID login and registration" for my newly installed Redmine deployment, but the checkbox under Administration -> Settings -> Authentication is disabled.

• OS: Ubuntu Server 12.04
• Redmine: 1.4.3.stable installed using Ondřej Surý's PPA
• Database: PostgreSQL 9.1.5

Ruby environment:

$ sudo -u www-data RAILS_ENV=production script/about

I installed ruby-openid by entering:

$ sudo gem install ruby-openid
Fetching: ruby-openid-2.2.0.gem (100%)
Successfully installed ruby-openid-2.2.0
1 gem installed
Installing ri documentation for ruby-openid-2.2.0...

The installed gems, visible to the apache user are:

$ sudo -u www-data gem list

*** LOCAL GEMS ***

ruby-openid (2.2.0)

Following the advice I'd seen in other discussions related to problems enabling OpenID, I ran the following as the apache user:

$ sudo -u www-data script/console production

>> Object.const_defined?(:OpenID)
=> false

I rebooted the server after installing the ruby-openid gem to make sure all the pieces got restarted.

Thanks in advance for any assistance.
