autenticar usuarios contra Directory Active o gmail

[Montes28]

Triby gracias por responder y se lo que dice el manual pero no me funciona.

Código HTML:

<form action="activo.php" method="post">
<input name="email" type="text" />
<input name="password" type="text" />
<input type="submit" value="enviar" />
</form>
 

Código PHP:

session_start(); #make sure this is at the top of your PHP file.
$adServer = "172.25.1.24"; #replace with your AD server ip/hostname
$ldapconn = ldap_connect($adServer)
or $this->msg = "Could not connect to LDAP server.";
 
 
$ldaprdn = $adServer . "\\" . $_POST["email"]; 
$ldapbind = ldap_bind($ldapconn, $ldaprdn, $_POST["password"]); 
 
 
if ($ldapbind) {
$msg = "Successfully Authenticated";
$_SESSION['email'] = $email;
$_SESSION['password'] = $password;
return true;
} else {
$msg = "Invalid email address / password";
return false;
}
 

y obtengo este error
Warning: ldap_bind() [function.ldap-bind]: Unable to bind to server: Can't contact LDAP server in C:\websites\activo\activo.php on line 9


y la linea 9 es $ldapbind = ldap_bind($ldapconn, $ldaprdn, $_POST["password"]);

nota le pregunte al administrador del DA acerca del ip y me respondio "debe configurar para que se conecte en conexión segura" a que se refiere?
