I have, together with SUSE service struggled some weeks in getting my SUSE SLED 12.2 Laptop on a Windows domain. For companies probably a usual situation.

Domain setup:

Above you find some tips how to do. SUSE is updating this documentation based on experiences with my case. Windows Server need to be prepared too, more than Windows demands.
Usually you need to try a little bit too.

I don't used SMB Information for user indentification since that made problems.
For the server access I produced bookmarks from manual link smb://server/drive. That work well.
