// This example contains an error, which we will catch.
$ld ldap_connect("localhost");
$bind ldap_bind($ld);
// syntax error in filter expression (errno 87),
// must be "objectclass=*" to work.
$res =  @ldap_search($ld"o=Myorg, c=DE""objectclass");
if (!
$res) {
    echo 
"LDAP-Errno: " ldap_errno($ld) . "<br />\n";
    echo
