Setting directory permissions when using Apache server

Hi
 I have successfully setup Subversion with LDAP using the wonderful
directions here
http://pteropus.blogspot.com/2008/04/securing-subversion-via-ldap.html

Does anyone have the combination of methods that will allow read-only
access to a tree?

I want to give the primary group full access, another group read-only
access, and remove everyone else's access.

Currently I have:

<Location /svn/main/>
    <LimitExcept MERGE MKCOL POST PUT DELETE PATCH PROPPATCH>
        Require group CN=Mygroup,OU=Security,DC=mycompany,DC=com
    </LimitExcept>
</Location>

This gives everyone read-only access, and mygroup full access.

We are running Subversion 1.5.5

Thanks!!
