Something

class User < ActiveLDAP::Base
        ldap_mapping :dnattr =>'uid', :prefix => 'ou=users',:classes => ['account','gidNumber','posixAccount','shadowAccount','top']
	belongs_to :groups, :class_name => 'Group', :foreign_key => 'memberUid', :local_key => 'uid'
end

================

@users = User.find_all(:attribute => 'title', :value => '07')

=============================

for user in @users
  user_str = user
  the_user = User.new("#{user_str}")
  the_user.gidNumber #outputs nothing
end

This for loop above doesn't work.

But this does...

for user in @users
  user_str = user
  the_user = User.new('fietka') #where fietka is a valid ldap user
  the_user.gidNumber #outputs 20000 - fietka's groupID
end
