[PHP] LDAP, Apache

[wiggum123]

Hey Guys an Girls

I am trying to write a PHP page to connect to one of my DC's to authenticate users. I havnt played with LDAP before and my knowledge of PHP is limited, so I'm a bit lost in the dark at the moment...
I have a Ubuntu server for the site, with the latest PHP, and I have told it to install LDAP, I wasnt sure if I had to do anything after installing it....
I have patched together a PHP script which connects to my server and binds successfully, apparantly. I then want to search for a user called ben and display his details, just to check everything is working.
It tells me I have connected using this;

 // LDAP variables
$ldaphost = "ldap://myserver/";  // your ldap servers
$ldapport = myport;            // your ldap server's port number
 
 
// Connecting to LDAP
$ldapconn = ldap_connect($ldaphost, $ldapport)
          or die("Could not connect to $ldaphost");
 
if ($ldapconn) {
 
    // binding to ldap server
    $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
 
    // verify binding
    if ($ldapbind) {
        echo "LDAP bind successful...$ldaprdn";
    } else {
        echo "LDAP bind failed...";
    }
 
} 
  

When I add the following code the page stops working and just goes white...

 $ds=dc2
$person = "ben"
$dn = "dc=mydomain, dc=local";
$filter="(|(sn=$person*)(givenname=$person*))";
$justthese = array("ou", "sn", "givenname", "mail");
 
$sr=ldap_search($ds, $dn, $filter, $justthese);
 
$info = ldap_get_entries($ds, $sr);
 
echo $info["count"]." entries returned\n"; 
  

What have I forgotten to configure? Is there another setting on the DC I need to enable??? Im Pulling my hair out and dont want to leave it unfixed on a Friday!

turn php error reporting on and use a proper browser like firefox and that will show you the error rather than a white screen.

Also if you use IIS + php you can use native integrate auth.

apache has a native ldap authentication module:
mod_auth_ldap - Apache HTTP Server

The first two lines of that second block of code look wrong to me.

$ds=dc2

Should that be $ds="dc2"; ?
I expect that line to be giving you a syntax error.

And the second line is missing it's semi-colon, which will also generate a syntax error.

Add
error_reporting['E_ALL'];
to the top of the code and run the it again.

Take the reporting line out when you're happy it's working.
