[horde] Cannot redeclare class Horde_Hooks

[meberhardt at unl.edu.ar]

Hi all,

When I try to enable the authusername horde hook, I get the following  
horde error:

"Cannot redeclare class Horde_Hooks"

I'm using a modified version of authusername:

         public function authusername ($userId, $toHorde)
                 {
                 $domain = $GLOBALS['auth_params']['imp_server_key'];
                 if ($toHorde) {
                         return  
ltrim(rtrim(Horde_String::lower($userId))) . '@' . $domain;
                 } else {
                         return (substr($userId, -strlen($domain)) == $domain)
                         ?  
substr(ltrim(rtrim(Horde_String::lower($userId))), 0, -strlen($domain))
                         : ltrim(rtrim(Horde_String::lower($userId)));
                 }
         }

What I'm doing wrong?

Thanks in advance,

Matías
