Redmine

I agree that the current support is a little wonky having just tried it out.

The OpenID register process should auto-register you with the site and ask for email, first and last name via the OpenID request. If the auth server does not provide that information, redirect to a form similar to the one mentioned above which only asks for the missing information. I know at the very least the google OpenID URL provides this information.

Getting the same running on 1.0.5 and 1.1.2... Using Google! :(

I think I know what's wrong... Here is URL to Google:

https://www.google.com/accounts/o8/ud?
  openid.assoc_handle=***********&
  openid.ax.mode=fetch_request&
  openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&
  openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&
  openid.mode=checkid_setup&
  openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&
  openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0&
  openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1&
  openid.realm=http%3A%2F%2Fdev.redmine.test%2F&
  openid.return_to=http%3A%2F%2Fdev.redmine.test%2Flogin%3F_method%3Dpost%26open_id_complete%3D1&
  openid.sreg.required=nickname%2Cfullname%2Cemail

Accordingly to Google there should be openid.ax.required instead of openid.sreg.required...

Ok... I found that changing the open_id_authenticate function to the following helps:

  def open_id_authenticate(openid_url)
    authenticate_with_open_id(openid_url, :required => [:nickname, :fullname, :email,
        'http://axschema.org/namePerson/first', 'http://axschema.org/namePerson/last', 'http://axschema.org/contact/email'
      ], :return_to => signin_url) do |result, identity_url, registration|
      if result.successful?
        logger.info " >>> registration: #{registration.inspect}" # FIXME
        user = User.find_or_initialize_by_identity_url(identity_url)
        if user.new_record?
          # Self-registration off
          redirect_to(home_url) && return unless Setting.self_registration?

          # Create on the fly
          user.login = registration['nickname'] unless registration['nickname'].nil?
          user.mail = registration['email'] unless registration['email'].nil?
          user.firstname, user.lastname = registration['fullname'].split(' ') unless registration['fullname'].nil?

          user.login = registration['http://axschema.org/contact/email'].first unless registration['http://axschema.org/contact/email'].nil?
          user.mail = registration['http://axschema.org/contact/email'].first unless registration['http://axschema.org/contact/email'].nil?
          user.firstname = registration['http://axschema.org/namePerson/first'].first unless registration['http://axschema.org/namePerson/first'].nil?
          user.lastname = registration['http://axschema.org/namePerson/last'].first unless registration['http://axschema.org/namePerson/last'].nil?

          user.random_password
          user.register

          case Setting.self_registration
          when '1'
            register_by_email_activation(user) do
              onthefly_creation_failed(user)
            end
          when '3'
            register_automatically(user) do
              onthefly_creation_failed(user)
            end
          else
            register_manually_by_administrator(user) do
              onthefly_creation_failed(user)
            end
          end          
        else
          # Existing record
          if user.active?
            successful_authentication(user)
          else
            account_pending
          end
        end
      end
    end
  end
