Hello, I've upgraded my redmine server from 1.3.X to 2.1.0, and encounted weird problem.

• Condition
  ** Redmine 2.1.0 with URI prefix (ex : http://my.server/redmine )
  ** On-the-fly creation enabled LDAP auth

• Problem
  ** Existing users can login with their ldap account.
  ** But when new users try to create a new one, redmine displays '404 not found' error.
  ** Redmine log

  Processing by AccountController#login as HTML
  Parameters: {"back_url"=>"http://[MyServerDomain]/redmine/projects/[MyProject]/wiki", "login"=>"로그인 »", "utf8"=>"✓", "password"=>"[FILTERED]", "username"=>"[new_user_id]", "authenticity_token"=>"[Token]"}
  Current user: anonymous
  Missing template, responding with 404
  Rendered common/error.html.erb within layouts/base (0.1ms)
  Completed 404 Not Found in 62ms (Views: 4.6ms | ActiveRecord: 0.0ms)
  

• Work around
  ** modify app/controllers/account_controller.rb

  
  def onthefly_creation_failed(user, auth_source_options = { })
  @user = user
  session[:auth_source_registration] = auth_source_options unless auth_source_options.empty?
  #render register_path <-- register_path's value : "/redmine/account/register"
  render "/account/register" # remove the prefix
  end
