I installed davfs2 on my rPi running piCore-6.1. I added a line with the desired mountpoint to /etc/fstab:
https://url.../ /path.../ davfs _netdev,rw,user,uid=1000,gid=1000 0 0
I also created a /etc/davfs2/secrets (and called chmod 600 on it) with
https://url.../ user password
When I call
mount -a I am asked to enter a username and password, as to my understanding davfs2 should check with the secrets file and use the specified user and password.
TL;DR My davfs2 doesn´t want to use the secrets file I created...
