Why some work with CNAMEs+SPN and some not that i dont know. 
But you can just add whats needed, as long the CNAME resolves that should also work. 

I dont use smblcient at all here so thats one i didnt know. 
So thanks on that one. :-) 

And small tip for people that dont use DNS at all. 
You can add cifs/ip_of_host at Realm also, if you use //ip_of_host/share 
But it less flexible.
