Active Directory/Connect

Active Directory/Connect
You are encouraged to solve this task according to the task description, using any language you may know.

The task is to establish a connection to an Active Directory or Lightweight Directory Access Protocol server.

AutoIt

Works with: AutoIt

<lang AutoIt> #include <AD.au3> _AD_Open()</lang>

AutoHotkey

Works with: AutoHotkey_L

Translation of: VBScript

<lang AutoHotkey>objConn := CreateObject("ADODB.Connection") objCmd := CreateObject("ADODB.Command") objConn.Provider := "ADsDSOObject" objConn.Open()</lang>

C

With OpenLDAP: <lang C>#include <ldap.h> ... char *name, *password; ... LDAP *ld = ldap_init("ldap.somewhere.com", 389); ldap_simple_bind_s(ld, name, password); ... after done with it... ldap_unbind(ld);</lang>

C#

<lang csharp> // Requires adding a reference to System.DirectoryServices var objDE = new System.DirectoryServices.DirectoryEntry("LDAP://DC=onecity,DC=corp,DC=fabrikam,DC=com"); </lang>

ColdFusion

<lang cfm> <cfldap server = "#someip#" action="query" start="somestart#" username = "#someusername#" password = "#somepassowrd#" name = "results" scope="subtree" attributes = "#attributeslist#" > </lang>

D

Based on dopenldap. <lang d> import openldap; import std.stdio;

void main() {

 auto ldap = LDAP("ldap://localhost");
 auto r = ldap.search_s("dc=example,dc=com", LDAP_SCOPE_SUBTREE, "(uid=%s)".format("test"));
 int b = ldap.bind_s(r[0].dn, "password");
 scope(exit) ldap.unbind;
 if (b)
 {
   writeln("error on binding");
   return;
 }

 // do something
 ...
   

} </lang>

Erlang

This needs a test case. Is there a LDAP server available? <lang Erlang> -module(ldap_example). -export( [main/1] ).

main( [Host, DN, Password] ) ->

{ok, Handle} = eldap:open( [Host] ),
ok = eldap:simple_bind( Handle, DN, Password ),
eldap:close( Handle ).

</lang>

F#

Translation of: C_sharp

For Active Directory we use the library System.DirectoryServices

<lang fsharp>let adObject = new System.DirectoryServices.DirectoryEntry("LDAP://DC=onecity,DC=corp,DC=fabrikam,DC=com")</lang>

For your average LDAP server we use System.DirectoryServices.Protocol

For a minimal example we make an anonymous connect to the local machine on the well-known LDAP port 389 <lang fsharp>let ldapServer = new System.DirectoryServices.Protocols.LdapDirectoryIdentifier("127.0.0.1") let connect = new System.DirectoryServices.Protocols.LdapConnection(ldapServer) connect.Bind()</lang>

Haskell

Example uses the ldap-client package:

<lang haskell>{-# LANGUAGE OverloadedStrings #-}

module Main (main) where

import Data.Foldable (for_) import qualified Data.Text.Encoding as Text (encodeUtf8) import Ldap.Client (Attr(..), Filter(..)) import qualified Ldap.Client as Ldap (Dn(..), Host(..), search, with, typesOnly)

main :: IO () main = do

   entries <- Ldap.with (Ldap.Plain "localhost") 389 $ \ldap ->
       Ldap.search ldap (Ldap.Dn "o=example.com") (Ldap.typesOnly True) (Attr "uid" := Text.encodeUtf8 "user") []
   for_ entries $ \entry ->
       print entry</lang>

Java

This code uses the Apache Directory third-party library.

<lang java>import java.io.IOException; import org.apache.directory.api.ldap.model.exception.LdapException; import org.apache.directory.ldap.client.api.LdapConnection; import org.apache.directory.ldap.client.api.LdapNetworkConnection;

public class LdapConnectionDemo {

   public static void main(String[] args) throws LdapException, IOException {
       try (LdapConnection connection = new LdapNetworkConnection("localhost", 10389)) {
           connection.bind();
           connection.unBind();
       }
   }

}</lang>

Kotlin

<lang scala> import org.apache.directory.api.ldap.model.exception.LdapException import org.apache.directory.ldap.client.api.LdapNetworkConnection import java.io.IOException import java.util.logging.Level import java.util.logging.Logger

class LDAP(map: Map<String, String>) {

   fun run() {
       var connection: LdapNetworkConnection? = null
       try {
           if (info) log.info("LDAP Connection to $hostname on port $port")
           connection = LdapNetworkConnection(hostname, port.toInt())

           try {
               if (info) log.info("LDAP bind")
               connection.bind()
           } catch (e: LdapException) {
               log.severe(e.toString())
           }

           try {
               if (info) log.info("LDAP unbind")
               connection.unBind()
           } catch (e: LdapException) {
               log.severe(e.toString())
           }
       } finally {
           try {
               if (info) log.info("LDAP close connection")
               connection!!.close()
           } catch (e: IOException) {
               log.severe(e.toString())
           }
       }
   }

   private val log = Logger.getLogger(LDAP::class.java.name)
   private val info = log.isLoggable(Level.INFO)
   private val hostname: String by map
   private val port: String by map

}

fun main(args: Array<String>) = LDAP(mapOf("hostname" to "localhost", "port" to "10389")).run() </lang>

Perl

LDAP Modules <lang perl> use Net::LDAP;

my $ldap = Net::LDAP->new('ldap://ldap.example.com') or die $@; my $mesg = $ldap->bind( $bind_dn, password => $bind_pass ); </lang>

PHP

PHP LDAP Reference <lang php><?php $ldap = ldap_connect($hostname, $port); $success = ldap_bind($ldap, $username, $password);</lang>

PicoLisp

Python

Works with: Python version 2.6

Library: python-ldap

python-ldap Documentation

<lang python>import ldap

l = ldap.initialize("ldap://ldap.example.com") try:

   l.protocol_version = ldap.VERSION3
   l.set_option(ldap.OPT_REFERRALS, 0)

   bind = l.simple_bind_s("me@example.com", "password")

finally:

   l.unbind()

</lang>

Racket

This version uses the ldap package, and was tested against OpenLDAP (with real values): <lang racket>#lang racket (require net/ldap) (ldap-authenticate "ldap.somewhere.com" 389 "uid=username,ou=people,dc=somewhere,dc=com" password)</lang>

Translation of: C

This is a direct translation of the C code -- I have no idea how to try it out since I don't have a working ldap server... So take it as a stub that waits for someone who can try it to do so. (And it's a low level thing anyway, there's an ldap package for Racket which I can't try for a similar reason.)

<lang racket>#lang racket

(require ffi/unsafe ffi/unsafe/define)

(define-ffi-definer defldap (ffi-lib "libldap")) (defldap ldap_init (_fun _string _int -> _pointer)) (defldap ldap_unbind (_fun _pointer -> _void)) (defldap ldap_simple_bind_s (_fun _pointer _string _string -> _int)) (defldap ldap_err2string (_fun _int -> _string))

(define name ...) (define password ...) (define ld (ldap_init "ldap.somewhere.com" 389)) (ldap_simple_bind_s ld name password)

(ldap_unbind ld)</lang>

Ring

<lang ring> see system("dir") + nl </lang>

Ruby

Similar to Tcl, assume the AD server talks LDAP.

There are many Ruby LDAP packages ([1]) -- this solution uses Net::LDAP ("Pure Ruby LDAP Tools" on RubyForge, gem name "ruby-net-ldap")

Library: RubyGems

<lang ruby>require 'rubygems' require 'net/ldap' ldap = Net::LDAP.new(:host => 'ldap.example.com', :base => 'o=companyname') ldap.authenticate('bind_dn', 'bind_pass')</lang>

Run BASIC

<lang runbasic>print shell$("dir") ' shell out to the os and print it</lang>

Scala

 <lang scala>import java.io.IOException

import org.apache.directory.api.ldap.model.exception.LdapException import org.apache.directory.ldap.client.api.{LdapConnection, LdapNetworkConnection}

object LdapConnectionDemo {

 @throws[LdapException]
 @throws[IOException]
 def main(args: Array[String]): Unit = {
   try {
     val connection: LdapConnection = new LdapNetworkConnection("localhost", 10389)
     try {
       connection.bind()
       connection.unBind()
     } finally if (connection != null) connection.close()
   }
 }

}</lang>

smart BASIC

smart BASIC uses three separate commands to list the current directory, folder and files respectively. <lang qbasic>PRINT "Current directory: ";CURRENT_DIR$() PRINT PRINT "Folders:" PRINT DIR "/" LIST DIRS a$,c FOR n = 0 TO c-1 PRINT ,a$(n) NEXT n PRINT PRINT "Files:" PRINT DIR "/" LIST FILES a$,c FOR n = 0 TO c-1 PRINT ,a$(n) NEXT n</lang>

Tcl

This does not use SSPI/Kerberos yet, so your AD would need to allow simple ldap access. <lang tcl>package require ldap set conn [ldap::connect $host $port] ldap::bind $conn $user $password</lang>

VBScript

Creating the normal connection to AD <lang vbscript>Set objConn = CreateObject("ADODB.Connection") Set objCmd = CreateObject("ADODB.Command") objConn.Provider = "ADsDSOObject" objConn.Open</lang>
