hi all,
I'm starting an application which uses OpenLDAP as the backend.

I've installed activeldap and its requirements, however i'm at a loss for
how to get it to work.
From looking at various examples, I've put this code together:

      1 require 'rubygems'
      2 require_gem 'log4r'
      3 require_gem 'ruby-activeldap'
      4
      5 class User < ActiveLdap::Base
      6   ldap_mapping
:dn_attribute=>'uid',:prefix=>'dc=office',:classes=>['staffAccount']
      7 end
      8 ActiveLdap::Base.establish_connection(
      9   :host    =>"192.168.1.27",
     10   :port    =>389,
     11   :bind_dn =>"cn=root,dc=office",
     12   :password=>"secret")
     13
     14 user = User.find("admin@office*")
     15 puts user.displayName
     16 user.displayName = "testing"
     17 unless user.save
     18   puts "failed"
     19   puts user.errors.full_messages
     20   exit 1
     21 end


everything goes ok upto line 15 - it prints the displayName of that record,
and i can print any other attributes. however, when i try to change
anything, i get this:
/usr/lib/ruby/gems/1.8/gems/ruby-activeldap-0.8.0/lib/active_ldap/adaptor/ldap.rb:288:in

I'm not sure what "No such object" is refering to? any thoughts?

thanks,
Ol.
