How can I connect to a DFS share on a Windows 2016 Server?

Question

My company host our data on a Windows Server 2016. I am running Xubuntu (version 15.04) and cannot get connected to our share using the mount command.

This is an example of command I unsuccessfully tried (I wanted to mount the folderFolder4underTest_mntin the example below):

sudo mount -v -t cifs //domain.adress.org/dfs/Folder1/Folder2/Folder3/Folder4 /home/alkalyzer/Test_mnt -o username=domain/myusername,domain=domain.adress.org,rw

While doing so (after having provided my password at the prompt), I received the following error message :

mount error(13): Permission denied

And this is what is written in/var/log/syslog:

Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE
CIFS VFS: Send error in SessSetup = -13
CIFS VFS: cifs_mount failed w/return code = -13

I followed different methods to try to get this to work:

1. Changingworkgrouptoworkgroup = DOMAIN in /etc/samba/smb.conf
2. Addingwins support = yes in /etc/samba/smb.conf
3. Adding bothclient min protocol = SMB2andclient max protocol = SMB3in /etc/samba/smb.conf

4. Adding these two lines in/etc/request-key.conf:

   create cifs.spnego  *   *       /usr/sbin/cifs.upcall -t %k
   create  dns_resolver    *   *       /usr/sbin/cifs.upcall %k
   

I can connect to this share by using a file-browser (Thunar or Nautilus) but I cannot browse the folder contained in/run/user/1000/gvfswhich corresponds to the remote folder (ls indicates that all permissions and ownerships are filled by question mark for this folder).

I can also connect to this share with smbclient with this command:

smbclient //domain.adress.org/dfs/ -Udomain/myusername -Whdomain.adress.org -D Folder1/Folder2/Folder3/Folder4

How can I mount these remote folders with the mount command?

Solution

I found a solution in this blog post

Install the keyutils package.

sudo apt-get install keyutils

Now I am able to mount the dfs share without a servername:

sudo mount -t cifs //mydfsdomain/namespaceroot/sharedfolder /mnt/sharedfolder -o credentials=/etc/cred.file
