How can I setup the Trac Repository authentication

I'm controlling the user authentication to the repository through apache.

So my dav_svn.conf is the following:

AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd
AuthzSVNAccessFile /etc/apache2/svn_access_control

And the svn_access_control is the following:

[groups]
team = jjtt
admin = robu

[/]
@team = rw


[/wlp]
@team = rw
@admin = rw


[/wesys]
@team = rw

I setup the trac login as well

   <LocationMatch "/trac/[^/]+/login">
      AuthType Basic
      AuthName "Trac"
      AuthUserFile /etc/apache2/dav_svn.passwd
      Require valid-user
    </LocationMatch>

But I want to control the access to the repository browsing as well. In trac I can control a few things, but not the repository access. How can I add to the trac the something like AuthzSVNAccessFile
