I just installed ActiveLdap, copied the plugin into vendor/plugins and  
setup a config/ldap.yml file. Starting rails gives me an error that it  
can not find the ldap source file. (I installed from the gem with its  
prerequisites log4r, etc.)

I have tried putting require’s in environment.rb without success. I am  
using current gems of rails. I have also tried to execute this in a  
non-rails program test program, but receive the same message there too.

I’m not sure which file it wants, but i see it here  
/usr/local/lib/ruby/1.8/uri/ldap.rb

Has anyone seen this type of error before and can offer a clue on how to  
resolve it?

Allen

Solved! I had not installed the prerequisite ruby-ldap library. This is  
not available as a gem so did not get installed as an active\_ldap  
dependency.

Hint: I had to install ruby-ldap from the the FreeBSD ports, and trying  
to install it from source was not working (configuration problems).
