Problem with TortoiseSVN

Hi;

I have installed TortoiseSVN and I have changed the file httpd.conf as
follows :

1- change the line
Require valid-user
to
<LimitExcept GET PROPFIND OPTIONS REPORT>
Require valid-user
</LimitExcept>

2- From the command prompt (DOS-Box), change to the apache2 folder and
create a password file by entering
   bin\htpasswd -bc passwd toto titi
This will create a file with the name passwd which is used for
authentication.

3- Restart the apache service
4- Point your browser to http://MyServer/svn
I have the following error message and the identification window for a
username and password the is not posted ?
Forbidden
You don't have permission to access /svn/ on this server.
Apache/2.0.48 (Win32) SVN/1.0.0 DAV/2 Server at localhost Port 80
But I have access to my repository :
Revision 0: /
Powered by Subversion <http://subversion.tigris.org/> version 1.0.0.
