Install davfs2
apt-get install davfs

Reconfigure davfs2 to allow access to other users (select ‘yes’ when prompted).
dpkg-reconfigure davfs2

Create a mountpoint
mkdir /mnt/owncloud

Mount the WebDav ownCloud
mount -t davfs https://owncloud_address_or_ip/owncloud/remote.php/webdav /mnt/owncloud

If your owncloud installation is in a directory other than ‘owncloud’ substitute it above. I used HTTPS which will encrypt communication and credentials but HTTP can also be used but obviously is higher risk.

Credentials can be automatically supplied by adding them to the following files

system wide /etc/davfs/secrets

individually ~/.davfs2/secrets

Edit either file using nano and add
https://owncloud_address_or_ip/owncloud/remote.php/webdav /mnt/owncloud USERNAME PASSWORD

To mount on boot add the following to fstab
https://owncloud_address_or_ip/owncloud/remote.php/webdav /mnt/owncloud davfs2 user,auto 0 0

(using noauto instead of auto will prevent it beingmounted automatically so choose depending on your enviroment)

To manually mount use
mount /mnt/owncloud

To unmount use
umount /mnt/owncloud

When I tried to create a test file on the shared I got the following error
touch: setting times of ‘test’: No such file or directory

To fix this edit your /etc/davfs2/davfs2.conf file and change/uncomment the ‘use_locks’ parameter to
use_locks 0
