Feature?: User mapping

[freswa]

Thanks for creating this nice piece of software. Maybe I'm too dumb to configure this correctly, but it seems to me I'm missing a few bits to replace my current nginx (mod dav) setup.

At the moment I'm mapping usernames to foldernames. E.g. if mike logs in, he sees the folder pictures, but it's mapped to the folder pictures_mike - same for user peter who sees pictures as well, but will be served pictures_peter. As stated in the example config, only the path variable is considered for the path, so neither can't I create a per-user folder and map the user folders in there nor can I incorporate the username in the foldername to serve.

Am I missing something?
