svn: PROPFIND 405 Method Not Allowed

Hi,

I try to use subversion with an https server.
This server run gforge and can only be reach by https.

My repository is OK : I can checkout on the file and I can view it with
viewcvs on the server.

But I can't check it out with svn : $ svn checkout
https://svn.<server_name>/svn/template1
I've got the error below :

svn: Échec de la requête PROPFIND sur '/svn/template1'
svn: PROPFIND de '/svn/template1': 405 Method Not Allowed
(https://svn.<server_name>)

(<server_name> is my server name)

I've already search on google and find informations on access rules, but
it's not the problem in my case.
I think about a bad configuration of my apache daemon.

Last line of /var/log/httpd/access_log :
<ip> - - [28/Jul/2006:11:11:46 +0200] "PROPFIND /svn/template1 HTTP/1.1"
405 332 "-" "SVN/1.3.1 (r19032) neon/0.25.5"

(<ip> is the ip my client machine)

What is the meaning of "332" is this log file ?

A part of my apache conf file :
<VirtualHost <server_name>:443>
        ServerName svn.<server_name>.org
        DocumentRoot /svnroot
  <[..]>
</VirtualHost>

/svnroot is the folder where template1 folder is on the server.

Perhaps I've had to add "svn." to the line "<VirtualHost <server_name>:443>"
Perhaps Something is missing to use these lines while the client access
to the /svn path on the http server ?

I don't know much how to configure apache yet.

Thanks for yours answers.
