I configured LDAP for SSL (LDAPS) on the Active Directory (AD) Domain Controller (DC).
The DC is a Windows 2003 Server box.

To do this I:
1) Setup the DC as a Certificate Authority (CA)
2) Issued a Certificate to itself
3) Issued a Certificate to the client that would be connecting via LDAPS

The client is configured in the following manner:
1) Windows 2003 Server Running IIS
2) PHP 5.0.4 installed
3) LDAP support enabled
    - Uncommented the php_ldap.dll extension
    - Copied the php_ldap.dll file into the appropriate directory
    - Restarted IIS

Using the LDP tool, I was able to connect and bind via ports 389, 636, and 3269.

Here is the code I am using to attempt the bind:


<?php

$host = "ldaps://server.addomain.domain.com";
$un = "jdoe";
$pw = "password";

$lc = ldap_connect($host);

ldap_set_option($lc, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($lc, LDAP_OPT_REFERRALS, 0);

$lb = ldap_bind($lc, $un, $pw);

ldap_close($lc);

?> 


If I change it to ldap://server.addomain.domain.com it functions correctly.

Is there a secure bind function I should know about?

Thanks for the help!
