通过ruby net-ldap查询LDAP用户的更好方法？

这是我目前要做的只是为了获得用户.

results = search :base => @base, :filter => Net::LDAP::Filter.eq("cn", "*")
  @results = Array.new

  results.each do |result|
    @results.push result if result[:objectclass].include? "person" unless result[:objectclass].include? "computer"

似乎会有更好的方法.我在文档中看不到任何明显的东西.

filter = Net::LDAP::Filter.eq("sAMAccountName", "*")
filter2 = Net::LDAP::Filter.eq("objectCategory", "organizationalPerson")

joined_filter = Net::LDAP::Filter.join(filter, filter2)

ldap.search(:base => treebase, :filter => joined_filter) do |entry|
    puts entry.sAMAccountName
end
