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 = 192.168.0.55 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
Stuff I'm Up To 
Hi, Can you start at the beginning and explain how you connect to a DFS share on a fresh install of RH Enterprise 9.x? What you installed, what files you configured, joining the domain etc. Thanks you very much.

This is a post from 5 years ago, back in the days of me working in an environment that was predominantly Windows and only me running Debian Linux on my desktop. These days I rarely encounter Windows, and I can’t really express how happy I am about that :) So I’m not in a position to require Samba, and have no Windows system I could test with.
I can’t really be specific with RedHat as it’s not a distro I’ve got great experience with. I can say that I won’t have installed anything more than samba fs (which should get you cifs-utils) ,and the keyutils mentioned in the linked article. Furthermore, I also would not have joined the Windows domain, I didn’t even use PAM LDAP, back then. I would have connected using mount as per the example:
“`shell
mount -t cifs //servername/sharename /mnt/temp –-verbose -o username=my_user_name,password=my_password,workgroup=DOMAIN_NAME
“`

With all that said, I can strongly recommend that you get the DNS part of Windows and your Linux client working properly. Ensure `resolv.conf` has your domain controllers listed and the search domain correct. Make sure you can resolve short names and fqdn’s.
Good luck in your endeavours.

Thanks very much for the reply. I found what I needed here:
https://access.redhat.com/solutions/45070 and combined it with the info you published and all worked well.
Thanks again.
