I’ve kicked this around a few times and resigned myself to just using the non-DFS path to attach to. But we’ve recently changed some of the servers around and the paths have changed – obviously the DFS paths haven’t. So I thought I’d have a go at fixing the problem.

SMB is obviously working as I can connect to the share using the traditional path //servername/sharename. But when trying to use the DFS version //domain.local/shares/sharename it would fail to find the share.

This post provided the answer to my problems: http://mattslay.com/connecting-ubuntu-to-windows-shares-and-dfs-trees/

I added wins into my /etc/nsswitch.conf:

hosts: files wins dns mdns4_minimal [NOTFOUND=return]

I know, I’m not using wins, we don’t have wins, but let’s go there.

Then I edited my /etc/samba/smb.conf and added/amended some wins details under the [global] section. Using one of the domain controllers as the IP address.

wins server =
name resolve order = host wins bcast

Finally changed the -c option in /etc/request-key.conf to -t on the cifs.spnego line.:

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

Now I can connect to the DFS path using the GUI file manager smb://domain.local/shares/sharename or using the command line to mount the share.

$ sudo mount -t cifs //domain.local/shares/sharename /mnt/sharename --verbose -o username=myuser,vers=2.0
