Redmine

We used to acces project documents from Windows Xp Explorer on our Subversion (Apache) which i set up from this howto Repositories_access_control_with_apache_mod_dav_svn_and_mod_perl. Since Windows 7 this does not work any more, because Windows 7 only works with AuthType Digest.
The problem is i don't know how to setup this together with ldap and redmine auth perls scripts.I can't find any howto or sucess story.
Is there a AuthDigestProvider Provider instead the AuthBasicProvider ?

<VirtualHost svn.domain.loc:443>
        RewriteEngine On
        ServerName svn.domain.loc

        PerlLoadModule Apache::Redmine
        PerlLoadModule Authen::Simple::LDAP

    <Location /svn>
                DAV svn
                SVNParentPath "/srv/svn" 
                SVNPathAuthz off
                LimitXMLRequestBody 0
                SVNAutoversioning On
                ModMimeUsePathInfo On

                Order deny,allow
                Deny from all
        Allow from redmine.domain.loc
        Allow from xxx.xxx.xxx
                Satisfy any

                PerlAccessHandler Apache::Authn::Redmine::access_handler
                PerlAuthenHandler Apache::Authn::Redmine::authen_handler

                AuthType Basic
                AuthName "- SVN Repository -" 
                Require valid-user

                ## for mysql
                RedmineDSN "DBI:mysql:database=redmine;host=localhost" 

                RedmineDbUser "redmine" 
                RedmineDbPass "******" 
                RedmineCacheCredsMax "50" 
        </Location>

Please help!
