[Samba] Using GPO to mount shares on Linux

My actual setup is:

   - 2 Domain Controller using Samba 4.7 stable (synced)
   - Multiple Windows Workstations that has joined the Domain without
   - 1 Linux server using Debian 8 with Samba 4.2 as Member Server joined
   also to that Domain

This setup is working as expected (some windows bugs hide network drives,
but is not samba problem). All workstations are able to login with domain
credentials, and connect to shared drives on Linux server (managed by GPO
and ACL).

Now I've an xUbuntu workstation that I want to join to that Domain and I've
used realm and sssd to the job. The basic setup works fine and:

   - I'm able to login with domain users credentials into the linux
   - I can get the domain data like for example users and groups, and even
   use domain data to manage autofs
   - I can mount shares stored on a DC using Kerberos authentication
   - I can connect to shares using smbclient using Kerberos authentication

My problem comes when I try to mount o connect to a share that is on Member
server from the xUbuntu workstation, that give me the errors I've commented
before. After your comments and research about SPN on google I think that
maybe is the problem, but for now I'm not able to test it.
