Owncloud 10.0.0 Local external storage missing

I just installed owncloud 10.0.0 release and I cant find the option to add local folders to users anymore. In owncloud 9.1.x you can add local folders from the external storage drop down menu and let users/groups access those folders.

Steps to reproduce
1. install/setup owncloud 10
2. go to setting/Admin Storage
3. click the Add storage drop down menu

Expected behaviour
Be able to add a local folder and let users access it.

Actual behaviour
Local folder missing from external storage

This got disabled by purpose for security reasons. It allows an ownCloud Admin to take over the system without the system administrator. You can enable it via config.php:

please, I have a problem very similar, but in my case does not appear the option of external storage via FTP, and in owncloud 9 was normal

@tecnologia This is off topic, but you can download the app from marketplace: https://marketplace.owncloud.com/apps/files_external_ftp
