Пример 1. Complete example of password check
<?php $ds=ldap_connect("localhost"); // assuming the LDAP server is on this host if ($ds) { // bind if (ldap_bind($ds)) { // prepare data $dn = "cn=Matti Meikku, ou=My Unit, o=My Company, c=FI"; $value = "secretpassword"; $attr = "password"; // compare value $r=ldap_compare($ds, $dn, $attr, $value); if ($r === -1) { echo "Error: " . ldap_error($ds); } elseif ($r === true) { echo "Password correct."; } elseif ($r === false) { echo "Wrong guess! Password incorrect."; } } else { echo "Unable to bind to LDAP server."; } ldap_close($ds); } else { echo "Unable to connect to LDAP server."; } ?>
