    Following on from Jeremy S's example.
    Instead of defining LDAP_OPT_DIAGNOSTIC_MESSAGE as 0x32 then using it, you can just use the option already defined as that value :)

    LDAP_OPT_ERROR_STRING

    Here is how to tell if an Active Directory user account expired:

    define('LDAP_OPT_DIAGNOSTIC_MESSAGE', 0x0032);

    ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
    ldap_set_option($conn, LDAP_OPT_REFERRALS, 0);

    $bind = ldap_bind($conn, $user, $pass);

    ldap_get_option($conn, LDAP_OPT_DIAGNOSTIC_MESSAGE, $extended_error);

    if (!empty($extended_error))
    {
        $errno = explode(',', $extended_error)[2];
        $errno = explode(' ', $errno)[2];
        $errno = intval($errno);

        if ($errno == 532)
            $err = 'Unable to login: Password expired.';
    }

    PHP 7.1 added support for configuring the LDAP CA/Cert environment directly, rather than relying on the environment variables. I noticed that a lot of people are having trouble getting this to work.

    The correct way is:
    $ds=ldap_connect("ldap.google.com"); 
    ldap_set_option(NULL, LDAP_OPT_X_TLS_CERTFILE, "/path/file.crt");
    ldap_set_option(NULL, LDAP_OPT_X_TLS_KEYFILE, "/path/file.key");
    ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
    ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
    ldap_start_tls($ds);
    ...
    ldap_close($ds);
