Can't get svn+ssh setup properly

["Mathieu Malaterre" <mathieu.malaterre@gmail.com>]

Hi there,

  I would like to avoid typing my password everytime I do a 'svn up'
on svn.debian.org. For this,   I have been reading:

http://subversion.tigris.org/faq.html#ssh-auth-cache

  Reading:

http://lists.debian.org/debian-devel-announce/2008/05/msg00004.html

  it looks like only RSA key are accepted. Therefore I generated a new
pair (I only had DSA type key):

$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/mathieu/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/mathieu/.ssh/id_rsa.
Your public key has been saved in /home/mathieu/.ssh/id_rsa.pub.
The key fingerprint is:
1f:8d:21:a2:44:2d:6b:dc:56:78:0c:7a:81:28:90:68 mathieu@mattbox
The key's randomart image is:
+--[ RSA 2048]----+
|+. ..oo+         |
|+E..o.o.+        |
|.. .o+oo. .      |
|   .+oo. . +     |
|   ...  S o .    |
|         . .     |
|          .      |
|                 |
|                 |
+-----------------+


I updated the .ssh/config file:

Host svn.debian.org
  Compression yes
  User malat-guest
  IdentityFile=/home/mathieu/.ssh/id_rsa

I can see that I have now two ssh keys:

$ ssh-add -l
2048 1f:8d:21:a2:44:2d:6b:dc:56:78:0c:7a:81:28:90:68  (RSA)
1024 4b:4d:91:2b:ff:e2:7e:8b:1c:a4:69:bb:da:e1:6b:99  (DSA)

I went to https://alioth.debian.org/, logged in, copy/paste id_rsa.pub
in my public key.... still absolutely no change. I am still required
to enter my password.

what am I doing wrong ?

Thanks
