I can reproduce with
  sudo mount -t davfs https://cloud1.exemple.com/WebDav/NESTOR/GERARD 
/mnt/webdav

and open a document with libreoffice in /mnt/webdav.
Open the document is OK but save failed with this message

Error while saving document template-CRA2
The object is not accessible
Impossible to access the object
because the user rights are insufficient.

It is ok with gedit, the text editor of my Ubuntu distribution.
