Hi All,

I am a new to ruby on rails… i would like to authenticate ruby site  
using LDAP … I followed the link  
[http://wiki.rubyonrails.org/rails/pages/HowtoAuthenticateViaLdap](http://wiki.rubyonrails.org/rails/pages/HowtoAuthenticateViaLdap)

but after mentioning require ‘activeldap’ in config file and start the  
webrick server it gives the following error message…
