Description:
------------
in PHP Versions prior to 4.3.3 you can loose session data after session_regenerate_id.
this occurs for example in older opera browsers with cookies disabled. and also in internet explorer.

you can succesfully login to auth-protected area. after reloading page you have to reenter credentials.

you have to store old session data in a var and then restore data after regenerating session id. see code snipped below.

workaround found on php.net at function session_regenerate_id

Test script:
---------------
you can use example in package documentation

fix setAuth Method in Auth.php with:

session_start();
$old_sessid = session_id();
session_regenerate_id();
$new_sessid = session_id();
session_id($old_sessid);
session_destroy();

$old_session = $_SESSION;
session_id($new_sessid);
session_start();
$_SESSION = $old_session;

Expected result:
----------------
stay authenticated!!

Actual result:
--------------
loosing auth status

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PEAR.

Dependancies have been updated to indicate that Auth requires PHP4.3.3 and higher to work securely
