{SSHA} for PHP

[Jack van Rock <kampflitchi@googlemail.com>]

Hi,
I want to modify a website-login-system (PHP) to check passwords which 
are deocoded with SSHA.
My script should compare the clear password, which I get from a FORM, 
with the SSHA-hash of the password, which is in the database (MySQL). 
The dates in the MySQL-DB comes from a LDAP.
This is my script:

<?php
   $password_sub       = "test";
       //Das Passwort erhalte ich über ein HTML-Formular
   $passsowrd_hash_db  = base64_decode("e1NTSEF9aH....");
       //Diesen base64-Hash erhalte ich aus der Datenbank.
       //Er wird gleich decodiert, da man daraus das $salt benötigt.
       //Dann hat er die Form {SSHA}hxtMi....
   $salt = base64_decode(substr($passsowrd_hash_db , 32));
       //Berechnung des $salt
   $hash = "{SSHA}" . base64_encode(pack("H*", 
sha1($password_sub.$salt)).$salt);
?>

But the script doesn't work, because the generated hash isn't the same 
as the hash from the database.

But I don't now, what's wrong?

May someone help me?
