Hello,

I’m using the yubikey with the fellowing script:

Code:
$yubi = new Auth_Yubico('42', 'FOOBAR=',1,1);
$auth = $yubi->verify($otp);
if (PEAR::isError($auth)) {
   print "<p>Authentication failed: " . $auth->getMessage();
   print "<p>Debug output from server: " . $yubi->getLastResponse();
} else {
   print "<p>You are authenticated!";
}


If there is an error PEAR::isError($auth) returns FALSE.

But $auth->getMessage() is set, e.g. REPLAYED_OTP.

This only concerns when I’m testing this with my web hoster. When testing everything with my local web server my system PEAR::isError($auth) returns TRUE if there is an error.


Code:

print_r from $auth my web hoster (PHP 5.3.10):

PEAR_Error Object
(
    [error_message_prefix] =>
    [mode] => 1
    [level] => 1024
    [code] =>
    [message] => REPLAYED_OTP
    [userinfo] =>
    [backtrace] => Array
        (
            [0] => Array
                (
                    [file] => /usr/local/lib/php/PEAR.php
                    [line] => 527
                    [function] => PEAR_Error
                    [class] => PEAR_Error
                    [object] => PEAR_Error Object
 *RECURSION*
                    [type] => ->
                    [args] => Array
                        (
                            [0] => REPLAYED_OTP
                            [1] =>
                            [2] => 1
                            [3] => 1024
                            [4] =>
                        )
[/code]


local web server (PHP 5.3.20):

[code]
PEAR_Error Object
(
    [error_message_prefix] =>
    [mode] => 1
    [level] => 1024
    [code] =>
    [message] => REPLAYED_OTP
    [userinfo] =>
    [backtrace] => Array
        (
            [0] => Array
                (
                    [file] => /Applications/MAMP/bin/php/php5.3.20/lib/php/PEAR.php
                    [line] => 533
                    [function] => PEAR_Error
                    [class] => PEAR_Error
                    [type] => ->
                    [args] => Array
                        (
                            [0] => REPLAYED_OTP
                            [1] =>
                            [2] => 1
                            [3] => 1024
                            [4] =>
                        )

[/code]




It’s no good idea, to trust in PEAR::isError($auth)


Now I’m using:

[code]
$yubi = new Auth_Yubico('42', 'FOOBAR=');
$auth = $yubi->verify($otp);
if ($auth !== true) {
   print "<p>Authentication failed: " . $auth->getMessage();
   print "<p>Debug output from server: " . $yubi->getLastResponse();
} else {
   print "<p>You are authenticated!";
}


Kind regards
Mario
