* sftp only is enabled, with authentication by key or password
* partially uploadloaded are not visible thanks to [`HiddenStores`](http://proftpd.org/docs/directives/linked/config_ref_HiddenStores.html)(in fact they are, but name starts with `.` )
* 5 failed login attempts will cause the host to be temporary banned
* support authentication against an external web service
# TODO
* only password login is enabled. enabling [`SFTPAuthorizedUserKeys`](http://www.proftpd.org/docs/contrib/mod_sftp.html#SFTPAuthorizedUserKeys) seems to break password only login
* log rotation
* make sure SFTPLog is useful (seems very verbose and does not contain more than stdout)
* make it easier to manage users ( using `mod_auth_web` against an ERP5 endpoint or accepting a list of user/password as instance parameter )
* allow configuring webhooks when new file is uploaded
