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
<lang AutoIt> #include <AD.au3> _AD_Open()</lang>
AutoHotkey
<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>
ColdFusion
<lang cfm> <cfldap server = "#someip#" action="query" start="somestart#" username = "#someusername#" password = "#somepassowrd#" name = "results" scope="subtree" attributes = "#attributeslist#" > </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>
Java

static { log_ = LoggerFactory.getLogger(RDirectoryLDAP.class); connection = null; ldapHostName = "localhost"; ldapPort = 10389; }
public static void main(String[] args) { try { if (log_.isInfoEnabled()) { log_.info("LDAP Connection to " + ldapHostName + " on port " + ldapPort); } connection = new LdapNetworkConnection(ldapHostName, ldapPort);
try { if (log_.isTraceEnabled()) { log_.trace("LDAP bind"); } connection.bind();
if (log_.isTraceEnabled()) { log_.trace("LDAP unbind"); } connection.unBind(); } catch (LdapException lex) { log_.error("LDAP Error", lex); } catch (IOException ex) { log_.error("I/O Error", ex); } } finally { if (log_.isTraceEnabled()) { log_.trace("LDAP close connection"); } try { if (connection != null) { connection.close(); } } catch (IOException ex) { log_.error("I/O Error on connection.close()", ex); } }
return; }
}</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, $password);</lang>
PicoLisp
<lang PicoLisp>(unless (=0 (setq Ldap (native "libldap.so" "ldap_open" 'N "example.com" 389)))
(quit "Can't open LDAP") )
(native "libldap.so" "ldap_simple_bind_s" 'I Ldap "user" "password")</lang>
Python
<lang python>import ldap
l = ldap.initialize("ldap://ldap.example.com") try:
l.protocol_version = ldap.VERSION3 l.set_option(ldap.OPT_REFERRALS, 0)
bind = l.simple_bind_s("me@example.com", "password")
finally:
l.unbind()
</lang>
Racket
This version uses the ldap package, and was tested against OpenLDAP (with real values): <lang racket>#lang racket (require net/ldap) (ldap-authenticate "ldap.somewhere.com" 389 "uid=username,ou=people,dc=somewhere,dc=com" password)</lang>
This is a direct translation of the C code -- I have no idea how to try it out since I don't have a working ldap server... So take it as a stub that waits for someone who can try it to do so. (And it's a low level thing anyway, there's an ldap package for Racket which I can't try for a similar reason.)
<lang racket>#lang racket
(require ffi/unsafe ffi/unsafe/define)
(define-ffi-definer defldap (ffi-lib "libldap")) (defldap ldap_init (_fun _string _int -> _pointer)) (defldap ldap_unbind (_fun _pointer -> _void)) (defldap ldap_simple_bind_s (_fun _pointer _string _string -> _int)) (defldap ldap_err2string (_fun _int -> _string))
(define name ...) (define password ...) (define ld (ldap_init "ldap.somewhere.com" 389)) (ldap_simple_bind_s ld name password)
(ldap_unbind ld)</lang>
Ring
<lang ring> see system("dir") + nl </lang>
Ruby
Similar to Tcl, assume the AD server talks LDAP.
There are many Ruby LDAP packages ([1]) -- this solution uses Net::LDAP ("Pure Ruby LDAP Tools" on RubyForge, gem name "ruby-net-ldap")
<lang ruby>require 'rubygems' require 'net/ldap' ldap = Net::LDAP.new(:host => 'ldap.example.com', :base => 'o=companyname') ldap.authenticate('bind_dn', 'bind_pass')</lang>
Run BASIC
<lang runbasic>print shell$("dir") ' shell out to the os and print it</lang>
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>
