[sork] problem to change passwd

[John-Patrick Obermeier]

hi,

i've a problem to change password with passwd.
 first my system and backend configuration:

horde 3.x
imp 4.0
passwd 2.1
IMAP/Cyrus with MySQL authentification
password with crypt encryption

backend.php:

$backends['sql'] = array (
    'name' => 'Horde Authentication',
    'preferred' => '',
    'password policy' => array(
        'minLength' => 3,
        'maxLength' => 8,
        'maxSpace' => 0,
        'minUpper' => 1,
        'minLower' => 1,
        'minNumeric' => 1
    ),
    'driver' => 'sql',
    'params' => array(
        'phptype'    => 'mysql',
        'hostspec'   => 'localhost',
        'username'   => 'mail',
        'password'   => '*****',
        'encryption' => 'crypt',
        'database'   => 'mail',
        'table'      => 'accountuser',
        'user_col'   => 'username',
        'pass_col'   => 'password'
    )
);

if i want to change the password, the SORK:passwd can not authorize the 
change. the error message is: "*Incorrect Password*".

thx for help
