ldap_bind() connectivity

Thanks to Jochem Mass for helping earlier to the string splitting.  Works
great (so far).  Now on to my next problem, which has to do with
ldap_bind().

 

I have the following code:

 

      $ldapconn = @ldap_connect($adServer);

      $ldapbind = ldap_bind($ldapconn, $ldapuser, $ldappass);

 

      if ($ldapbind) {

        /** Successful authentication **/

        $_SESSION['username'] = $username;

        $_SESSION['password'] = $password;

      } else {

        /** Authentication failure **/

        $form->setError($field, "« Invalid username or password
»");

      }

      ldap_unbind($ldapconn);

 

The problem with this is that if the ldap_bind() fails in the second line,
it instantly spits text out to the browser:

 

Warning: ldap_bind() [function.ldap-bind
<http://www.smartroute.org/contest/include/function.ldap-bind> ]: Unable to
bind to server: Invalid credentials in /home/contest/include/session.php on
line 351

 

And because it does that, it never reaches the if routine right below it and
everything just bombs.  If I call it with @ldap_bind($ldapconn .) nothing
happens.  The error message gets suppressed but it also doesn't do anything
with the if routine afterwards.  It's almost like $ldapbind isn't getting
set at all.

 

What am I missing here?
