ldap_bind always returning true

Question

I'm attempting to implement LDAP user authentification however for some reason no matter what the input is, ldap_bind always returns true. Whether the input is gibberish, empty, or legitimate

$ds = ldap_connect($ldaphost)
      or die("Could not connect to $ds");

if($bind = ldap_bind($ds,$username, $password)) 
{
  // login successful
} 
else {
  // error message
}

any ideas?

note: using the code below produces the same issue:

$bind = ldap_bind($ds,$username, $password);

if($bind) 
{
  // login successful
} 
else {
  // error message
}

Thanks in advance!

Answer 1

Just do like this...

 if(ldap_bind($ds,$username, $password))

instead of

if($bind = ldap_bind($ds,$username, $password))
