ldap-activerecord-gateway
=========================
This is an implementation of an LDAP server which uses active record as the data source.
The server is read-only, and can serve information from any AR model that implements the
#search(string) class method and the #to_ldap_entry instance method.
To use, configure the server by creating a conf/ldap-server.yml file (see ldap-server.example.yml).
The important bits are rails_dir, active_record_model, basedn, and port.  Once that's done,
run "./bin/ldap-server.rb start", wait for it to daemonize, and check the log file under $RAILS_ROOT/log/ for
errors.  To stop, run "./bin/ldap-server.rb", and if you reconfigure the server or change the underlying
AR model, restart it with "./bin/ldap-server.rb restart".
To test, point your addressbook (ie: Thunderbird or OS X Address Book) at the server and run a search.
Example AR class:
class Person < ActiveRecord::Base
  def fullname
    "#{firstname} #{lastname}"
  end
  def to_ldap_entry
    {
      "objectclass"     => ["top", "person", "organizationalPerson", "inetOrgPerson", "mozillaOrgPerson"],
      "uid"             => ["tbotter-#{id}"],
       "sn"              => [lastname],
      "givenName"       => [firstname],
      "cn"              => [fullname],
      "title"           => [title],
      "o"               => [company],
      "mail"            => [email],
      "telephonenumber" => [work_phone],
      "homephone"       => [home_phone],
      "fax"             => [fax],
      "mobile"          => [mobile],
      "street"          => [address],
      "l"               => [city],
      "st"              => [state],
      "postalcode"      => [zip],
    }
  end
  def self.search(query)
    Person.find(:all,
                :conditions => ["(email LIKE ?) OR (firstname LIKE ?) OR (lastname LIKE ?)",
                                "#{query}%", "#{query}%", "#{query}%"])
  end
end
Have fun.
