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

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()

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>
