The Plesk interface does not support the webdav protocol. But Apache does support webdav. Webdav can be used as an iDisk under MacOS X. Webdav can also be used with Linux or Windows. Here are the steps to get webdav up and running. These instructions should work on Debian based system. But similar commands should work with all major Linux distributions:

First activate the webdav Apache modules and restart apache:

a2enmod dav
a2enmod dav_fs
service apache2 restart

Then create a vhost config for the domain you are using adding webdav. Please replace domain.tld with you domain. And check the directory line:

vi /var/www/vhosts/domain.tld/conf/vhost.conf

<Directory /var/www/vhosts/domain.tld/httpdocs>
DAV on
</Directory>

To get Plesk to include our custom configuration we must reconfigure the domain with the httpdmng.

/usr/local/psa/admin/sbin/httpdmng --reconfigure-domain domain.tld

This will make Plesk include the file vhost.conf in our Apache configuration adding the webdav directive.

You should be able to connect to the web share (webdav) now. Using the user name and password of the domain user in Plesk. You can either use the MacOS X finder (connect to server). Or you can also connect through most Linux desktops using Nautilus for example. If you experience any problems writing to the share. You may need to change the permissions on the folder so that the Apache user has write permissions:

chown -R www-data:www-data /var/www/vhosts/domain.tld/httpdocs/

Thats it you have created your own web share.
