ssh a devenir FOU

Je tente actuellement de realiser une connexio SSH entre un pc winXP pro et un serveur linux fedora8 mais je me confronte a un pb que je n'arrive pas a résoudre depuis 24H
Pour realiser la connexion , je genere d'abord les clefs public et prive id_dsa puis je les envoie au serveur via le script suivant:

Code:

cls
echo off
 
set /p login=Entrer votre login linux: 
set /p passwd=Entrer votre mot de passe linux: 
set serverlinux=10.1.2.237
set keyfilename=id_rsa
 
REM genere les clefs de type RSA en local
REM -N "" : permet de ne pas taper la Passphrase
ssh-keygen -t rsa -f %keyfilename% -N ""
 
 
 
REM envoie la clef public sur le serveur Linux
 
pscp -pw %passwd% %keyfilename%.pub %login%@%serverlinux%:.ssh/authorized_keys2

Ce script fonctionne tres bien et stock correctemen la clef publique id_rsa sur le serveur dans le repertoire /home/kassim/.ssh/authorized_keys2

Ensuite je lance la commande ds une fenetre DOS:
ssh -i "C:\Documents and Settings\User\Bureau\id_rsa" kassim@10.1.2.237

et la, impossible de se connecter sans qu'il me demande le password !!!!!!!
Ce qui est un probleme, il faut absolument que je puisse me connecter avec ce systeme de clefs prives/public pour pouvoir utiliser des scripts RSYNC (en autre)!!
Même apres avoir modifier le fichier sshd_config sur le serveur comme j'ai pu voir sur de nombreux tutos, le probleme persiste. Voici d'ailleurs ce fichier:
