..well I'm in trouble getting a core file, I have to check that.
But for now I just removed the TZ relevant parts from Horde.php so  
that I can at least go on with the original problem of this ticket.

I double checked everything, but still the  
_username_hook_frombackend() hook gets called again on a already  
"realmed" username:

Here is the code for the username hooks that I'm using:

if (!function_exists('_username_hook_frombackend')) {
      function _username_hook_frombackend($userID)
      {
          $servers = Horde::loadConfiguration('servers.php', 'servers', 'imp');
          $server_key = null;
          $vrealm = null;
          foreach ($servers as $key => $val) {
             if($servers[$key]['server'] == $_SESSION['imp']['server']) {
                 $vrealm = '@' . $key;
             }
          }
          if(empty($vrealm)) {
             $vrealm = '@' . Util::getFormData('server_key');
          }
          if (substr($userID, -strlen($vrealm)) == $vrealm) {
             $log_msg = '_username_hook_frombackend called for user "'  
. $userID . ' - not modifying "';
          } else {
             $log_msg = '_username_hook_frombackend called for user "'  
. $userID . ' - adding "' . $vrealm . '"';
             $userID = $userID . $vrealm;
          }
          Horde::logMessage($log_msg, __FILE__, __LINE__, PEAR_LOG_DEBUG);
          return $userID;
      }
}

if (!function_exists('_username_hook_tobackend')) {
      function _username_hook_tobackend($userID)
      {
          $fullusername = split('@', $userID);
          $log_msg = '_username_hook_tobackend called for user "' .  
$userID . ' - removing "' . $fullusername[1] . '"';
          Horde::logMessage($log_msg, __FILE__, __LINE__, PEAR_LOG_DEBUG);
          return $fullusername[0];
      }
}

In this code there is a workaround that prevents the addition of the  
realm if it is already added, but still that's just a workaround.

As client I'm using Thunderbird/Lighting 0.9

On authentication prompt I enter:
Username: myuser
Password: mypassword

attached is a horde debug log with all the entries I get when I  
connect with Lightning.
