https 访问subversion的问题

我配置用https访问subversion,配置文件如下:
NameVirtualHost 192.168.16.36:443
<VirtualHost 192.168.16.36:443>
        ServerAdmin webmaster@localhost
        SSLEngine On
        ServerName 192.168.16.36
        #SSLCertificateFile /etc/apache2/apache.pem
        SSLCertificateFile /etc/apache2/server.crt
        SSLCertificateKeyFile /etc/apache2/server.key

        ErrorLog /var/log/apache2/svn-ssl-error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog /var/log/apache2/svn-ssl-access.log combined
        ServerSignature off

        #for svn setup
        <Location />
          DAV svn
          SVNPath /opt/svn_repos/
          SVNPathAuthz off

        # our access control policy
        #AuthzSVNAccessFile /path/to/access/file

        # only authenticated users may access the repository
        Require valid-user

        # how to authenticate a user
        AuthType Digest
        AuthName "linkist"

        AuthUserFile /opt/trac/users.htdigest
        </Location>



</VirtualHost>
可是一直报错,到日志文件看是这样的
[Tue Apr 08 14:00:11 2008] [crit] [client 192.168.16.221] configuration error:  couldn't check user.  No user file?: /
