Mounting a webDAV share for all users

Question

I'm trying to mount a webDAV share with this fstab line:

myserverip /media/myserver/ davfs noauto,user,rw 0 0

I have added the secret credentials to ~/.davfs2/secrets.

Also done sudo dpkg-reconfigure davfs2 to allow mounting by non-root users.

This all works fine if I have the following in /etc/davfs2/davfs2.conf:

dav_user        myusername         # system wide config file only
dav_group       myusername         # system wide config file only

But this obviously only works for one user, however if I leave it at the default:

dav_user        davfs2           # system wide config file only
dav_group       davfs2           # system wide config file only

and add my user account to the group davfs2 via

sudo usermod -aG davfs2 myusername

which is successful as shown by the output of groups myusername:

myusername : myusername davfs2

However when I now try to mount the share I get the following error:

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

So how do I get it to mount by group and why does it not recognize that I’m in the correct group.

Answer 1

Your running login session might not be updated with the new group yet. Try just calling groups and see if that lists davfs2.

$ sudo useradd foo -M
$ groups
myuser adm cdrom sudo dip plugdev lpadmin sambashare
$ sudo usermod -aG foo myuser
$ groups
myuser adm cdrom sudo dip plugdev lpadmin sambashare
$ su -l myuser
$ groups
myuser myuser adm cdrom sudo dip plugdev lpadmin sambashare foo
