Jeremy,
LDAP authentication happens in two stages: connect and bind. The connect
stage is just establishing a connection with the LDAP server
(ldap_connect()). No username or password is necesary in this stage.
Once your connection is established, you attempt a bind (ldap_bind())to
verify a username/password on the LDAP server. Here's some PHP code that
will do it or you:
<?php
$ldap_server = "example.com"; // change to your LDAP server host name
$ldap_port = 389; // might be different for your server
$pw = "yourpassword"; // change to your password
$dn = "cn=dave,ou=people,dc=example,dc=com"; // change to the dn you want to authenticate
$connect_result = ldap_connect( $ldap_server, $ldap_port );
// Did we connect?
if( ! $connect_result )
{
echo "Could not connect to '$server_name' on port '$server_port'";
}
$bind_result = ldap_bind( $connect_result, $admin_dn, $admin_pw );
// Did we bind?
if( ! $bind_result )
{
echo "Bad username/password";
}
else
{
echo "Correct username/password!";
}
?>
Here's some good documentation on the topic:

Let us know how it goes.
