Problem new user using LDAP authentication - Redmine

ruby-enterprise-1.8.7-2012.02 使ったら redmine が と同じエラーになった。 ruby-enterprise-1.8.7-2011.03 に下げたら動いた。

Looking for logs the only information I have is: @ NoMethodError (undefined method `[]' for false:FalseClass): app/controllers/users_controller.rb:107:in `create' thin (1.3.1) lib/thin/connection.rb:80:in `pre_process' thin (1.3.1) lib/thin/connection.rb:78:in `catch' thin (1.3.1) lib/thin/connection.rb:78:in `pre_process' thin (1.3.1) lib/thin/connection.rb:53:in `process' thin (1.3.1) lib/thin/connection.rb:38:in `receive_data' eventmachine (0.12.10) lib/eventmachine.rb:256:in `run_machine' eventmachine (0.12.10) lib/eventmachine.rb:256:in `run' thin (1.3.1) lib/thin/backends/base.rb:61:in `start...
