Use umount command to unmount the WebDAV share.

Mount WebDAV share using fstab

Create fstab entry to allow the specified user to mount the filesystem.

You can mount the above-mentioned WebDAV share using sudo utility.

Additional notes

If you try to mount it as regular user and encounter the following error, then you need to set SUID bit on the mount.davfs binary.

$ mount /mnt/dav/sbin/mount.davfs: program is not setuid root

Execute dpkg-reconfigure to reconfigure davfs2 package, set the SUID bit and allow unprivileged users to mount WebDAV resources.

$ sudo dpkg-reconfigure davfs2

Reconfigure davfs2 package

In addition, user must be a member of the davfs2 group.

$ mount /mnt/dav

/sbin/mount.davfs: user must be member of group davfs2

Use the following command to add specified user to required group.

$ sudo usermod -a -G davfs2
