You can mount WebDAV Folders with the Linux tool fusedav using the user space mount arcitecture “fuse”:

fusedav https://my.server/my_folder /my/mountpoint

The suprise to me was that

1. fusedav will stay in foreground
2. fusedav will not ask for credentials at startup, but when used the first time (e.g. ls /my/mountpoint in another shell.

Both is uncommon for fuse modules.
