It doesn't say the url is incorrect it says that you failed authentication. I assume you followed the wiki article exactly?

in most cases, you should call zimbra preauth login via program(php, java, jsp....), cause you need to pass several parameters to zimbra (some of them need to be calculated first) :

1. email account
2. time (in mini-second format? if i remember correctly)
3. hash-key value (using SHA1?)

as Phoenix said, everything is written in that Preauth wiki article.

yeah i already COPY and Paste the code from the wiki and its not working

[tiger2000]

you should modify it before you use it, and nobody knows what code you got from the wiki?

Same applies for me: preauth is not working, but did work before upgrading 5.0.x to 6.0.4!

PHP Code:

<?php

    session_start();
    if ($_SESSION['authenticated'] == true && $_SESSION['auth_type'] == 'internal') {
        /**
        * Globals. Can be stored in external config.inc.php or retreived from a DB.
        */
        $PREAUTH_KEY="1234567890123456789012345678901234567890123456789012345678901234";
        $WEB_MAIL_PREAUTH_URL="https://myzimbra/service/preauth";
        
        /**
        * User's email address and domain. In this example obtained from a GET query parameter. 
        * i.e. preauthExample.php?email=user@domain.com&domain=domain.com
        * You could also parse the email instead of passing domain as a separate parameter
        */
        $user = $_SESSION['UserLogin'];
        $domain="mydomain";
        
        $email = "{$user}@{$domain}";
    
        if(empty($PREAUTH_KEY)) {
            die("Need preauth key for domain ".$domain);
        }
        
        /**
        * Create preauth token and preauth URL
        */
        $timestamp=time()*1000;
        $preauthToken=hash_hmac("sha1",$email."|name|0|".$timestamp,$PREAUTH_KEY);
        $preauthURL = $WEB_MAIL_PREAUTH_URL."?account=".$email."&by=name&timestamp=".$timestamp."&expires=0&preauth=".$preauthToken;
        
        /**
         * Redirect to Zimbra preauth URL
         */
        //die($preauthURL);
        header("Location: $preauthURL");
    } else {
        header("Location: http://mydomain/index.php");
    }
?>

I also tried to solve the issue by creating a new preauthentication key and restarting Zimbra - still authentication failed although I can use it from the Admin UI.

Has the URL based mechanism been changed or removed without notifiying users...?
