PHP and Active Directory

[andyt_2000_uk@yahoo.co.uk]

Hi

I'm trying to get it so visitors to our intranet site are able to log
into the site with there normal login details. On a network using
win2k3, active directory etc.

Now my code at the moment seems to connect to AD but it fails when it
trys to bind.

<?php
//Connect to Active Directory
$ad = ldap_connect("h ole.chase.local , 389") or
die("Couldn't connect to AD!"."<br />");
echo "connect result is " . $ad . "<br />";

//set protocol version
if (ldap_set_optio n($ds, LDAP_OPT_PROTOC OL_VERSION, 3)) {
echo "Using LDAPv3". "<br />";
} else {
echo "Failed to set protocol version to 3";
}

$ldaprdn = 'andy';
$ldappass = 'password';

//Bind to Active Directory
if ($ad){
$bd = ldap_bind($ad, $ldaprdn, $ldappass) or
die("Couldn't bind to AD!");
}
if ($bd){
echo "success"." <br />";
} else {
echo "fail"."<br />";
}
?>

Everytime it runs it dies, saying Couldn't bind to AD!

Checking the logs for apache i notice it reports

[client 127.0.0.1] PHP Warning: ldap_bind(): Unable to bind to
server: Can't contact LDAP server in F:\\Website\\ht docs\\example3. php
on line 23

Any ideas on how to solve this would be great.

Cheers

Andy

Of course it does... Consider a few changes to your code:

//Connect to Active Directory
$ad = ldap_connect('h ole.chase.local ', 389)
// First change ^^^^^^^^^^^^^^^ ^^^^^^^^
or die("Couldn't connect to AD!"."<br />");
echo "connect result is " . $ad . "<br />";
//set protocol version
if (ldap_set_optio n($ad, LDAP_OPT_PROTOC OL_VERSION, 3)) {
// Second change ^^
echo "Using LDAPv3". "<br />";
} else {
echo "Failed to set protocol version to 3";
}
$ldaprdn = 'andy';
$ldappass = 'password';
//Bind to Active Directory
if ($ad) {
$bd = ldap_bind($ad, $ldaprdn, $ldappass)
or die("Couldn't bind to AD!");
}
if ($bd) {
echo "success"." <br />";
} else {
echo "fail"."<br />";
}

Cheers, didn't spot those 2 mistakes.

Unfortunately i still get the same errors of not being able to bind to
AD.

Try changing:
die("Couldn't bind to AD!");
to:
die("Couldn't bind to AD: " . ldap_error($ad) );

As it is, you're suppressing all the useful information that might help
you solve the problem.

Re: PHP and Active Directory

May be your server name is not correct
try using

$ds = ldap_server("lo calhost");

or

$ds = ldap_server("ld ap://localhost");

if you are doing it on the server it self otherwise look for the
correct name that could be the problem as well....

Re: PHP and Active Directory

Cheers all for the help, it appears there was a DNS issue on the 2k3
box and so the ldap server name wasn't getting resolved.
