This pretty much matches my observations with domain based dfs. It's a
hit and miss with lots of poking around in the dark.
Occasionally it works and all looks very nice, but then on the next
login it might fail again. For me it was mostly failing.
(But then again I suspect it had to do with my removing one of the AD
DCs and downgrading it to a normal member server. I've seen the former
AD pop up in one of the DFS tabs as dfs root even though it wasn't a DC
Once DFS failed in the observed way, there is no point in logout/login
The only thing that *sometimes* helps is a complete reboot of the client
and hoping for the best.
This makes debugging the problem a very frustrating and time consuming
Also smbclient and windows 7 show very different behavior.
In smbclient I can always at least see the dfs directory but access to
the visible shares will fail.
$ smbclient -U sample12 '\\domain.local\dfs'
Enter sample12's password:
Domain=[DOMAIN] OS=[Unix] Server=[Samba 4.1.9-Debian]
smb: \> ls

In Windows 7 I can see the dfs share when I go to \\domain.local\ but
changing into that \\domain.local\dfs share results in an error.
In contrast to this, access via \\addchost.domain.local\dfs works
reliably from Windows and smbclient alike.
Using this form I can even use smbclient with Kerberos authentication.
(which fails for "domain.local" as there is no service principle for
cfis/domain.local at DOMAIN.LOCAL in the Kerberos database.)
I'll put that topic away for now.
