Redmine

I am attempting to configure LDAP, my configuration is as follows:

bash-3.2$ RAILS_ENV=development script/about
GLoc v1.1 running in development mode. Strings can be modified at runtime.
About your application's environment
Ruby version 1.8.7 (x86_64-linux)

I am using default port 389, and when trying to login I am getting this error:

OpenSSL::SSL::SSLError in AccountController#login

I do not want to use SSL/encryption to authenticate, how do I disable it?
