Thanks for your advice. I removed almost everything from the file  
hooks.php.dist so there is only this function left:

// USERNAME HOOK: See above for description of format.
     public function authusername($userId, $toHorde)
     {
         // Example #2: Convert username to all lowercase. This might be
         // necessary if an authentication backend is case insensitive to
         // take into account that Horde's preference system is case
         // sensitive.
         // ex. $userId = 'MyName' returns: 'myname'
         return $toHorde
             ? Horde_String::lower($userId)
             : $userId;
     }

I called the file hooks.php, is that okay? Or is it removed during  
upgrades and has to be named hooks.local.php? Do I have to "activate"  
the hooks.php-file or does Horde read it when it is present?
