I have an Active Directory server and a Windows WAMP server hosting PHP web applications that need to be able to authenticate to Active Directory using Kerberos.
I was able to easily connect and bind to the Active Directory host using some sample PHP code, but I'm not sure how to do so with Kerberos. I have see many forums and blogs detailing how to do this on *NIX machines, but that doesn't help me with my situation.
I did use Wireshark and Fiddler to confirm that there is no Kerberos or NTLM negotiating happening.
Sample code I used to connect and bind to LDAP:
<?php
$ldaphost = "example.domain.com";
$ldapport = 389;
$ldapuser = "user";
$ldappass = "password";
$ldapconn = ldap_connect( $ldaphost, $ldapport )
or die( "Unable to connect to the LDAP server {$ldaphost}" );
if ($ldapconn)
{
$ldapbind = ldap_bind($ldapconn, $ldapuser, $ldappass);
if ($ldapbind)
{
echo "LDAP connection successful";
}
else
{
echo "LDAP connction failed";
}
}
?>
Any help will be greatly appreciated, thanks!
Update: I've been wrestling with this all day and I think I need to use ldap_sasl_bind(), possibly using GSSAPI as the mechanism... No matter what parameters I put in to ldap_sasl_bind(), I get the following error: 'Unable to bind to server: Unknown authentication method'
I'm not sure how to implement GSSAPI, but some examples I've seen show using ldap_start_tls(), but I keep getting a 'Unable to start TLS: Server is unavailable' error.
I don't know if anyone knows anything about ldap_sasl_bind() (which is undocumented by PHP) or ldap_start_tls, but if this is the way I should be going, please point me in the right direction.
