This provides PHP with what it needs to make use of ldaps:// connections.Įxtract your Root CA certificate from Active Directory, this is achived through the use of Certificate Services, a startard component of Windows 2000 Server, but may not be installed by default, (The usual Add/Remove Software method will work here). Make sure you compile OpenLDAP with OpenSSL support, and that you compile PHP with OpenLDAP and OpenSSL. Hope this proves fruitfull for others like me when you couldn't find answers out there. Therefore, for those wishing to securely connect to Active Directory, from a Unix host using PHP+OpenLDAP+OpenSSL I spent some time getting this going myself, and came across a few gotcha's. passwords can only be changed using LDAPS connections to Active Directory. You cannot add objects or modify certain properties without LDAPS, e.g. Otherwise Active Directory provides a mostly readonly connection. To be able to make modifications to Active Directory via the LDAP connector you must bind to the LDAP service over SSL. $ldapconn = ldap_connect($dc) or die("DC N/A, PLEASE TRY AGAIN LATER.") Īlso with this approach, you get a real nice failover functionality, take for an example a company with a dozen of DC-a distributed along distant places, this way your PHP program will always have high availability if at least one DC is active at present. now, ldap_connect would certainly connect succesfully to DC tested previously and no timeout will occur If (!$dc) exit("NO DOMAIN CONTROLLERS AVAILABLE AT PRESENT, PLEASE TRY AGAIN LATER!") //user being notified after this loop, either there will be at least one DC which is available at present, or $dc would return bool false while the next line stops program from further execution

Return 1 //DC is up & running, we can safely connect with ldap_connect $op = fsockopen($host, $port, $errno, $errstr, $timeout) įclose($opanak) //explicitly close open socket connection If you don't want your PHP program to wait XXX seconds before giving up in a case when one of your corporate DC have failed, and since ldap_connect() does not have a mechanism to timeout on a user specified time, this is my workaround which shows excellent practical results.įunction serviceping($host, $port=389, $timeout=1)
