I only want to allow anonymous access to a virtual server.

Use a <Limit LOGIN> block to deny access at the top-level of the virtual host, then use <Limit LOGIN> again in your <Anonymous> block to allow access to the anonymous login. This permits logins to a virtual anonymous server, but denies to everything else. Example: <VirtualHost> ServerName "My virtual FTP server" <Limit LOGIN> DenyAll </Limit> <Anonymous /usr/local/private> User private Group private <Limit LOGIN> AllowAll </Limit> ... </Anonymous> </VirtualHost>
