A setup on howto improve your samba network and simplify it. 
This is how i setup, sure looks dificult but its all about DNS setup and what you add to it. 

For AD-DC.s  ( AD, TIME, NS, LDAP )
Hostname.FQDN.TLD : max 63chars, incl the .'s  allowed chars: a-Z 0-9 - 

Hostname : sam-dc1.internal.domain.tld
IP 	   : what you need/want. ( example ) 
PTR 	   :
CNAME    : dc1 ns1 ldap1 ntp1

Hostname : sam-dc2.internal.domain.tld
IP 	   : what you need/want. ( example ) 
PTR 	   :
CNAME    : dc1 ns2 ldap2 ntp2

For a MEMBER. 
Hostname.FQDN.TLD : max 254chars, incl the .'s  allowed chars: a-Z 0-9 - 
Hostname : sam-mem1.internal.domain.tld
IP 	   : what you need/want. ( example ) 
PTR 	   :
CNAME    : fs1 (fileserver1) 
But also and this is just how may servers you setup. 
Think in web1 proxy1 cluster1  etc etc. these are always the ALIASES. 
And you can also say thing like this. 

Why.. This is all about the ability to scale you network and split up services over other servers IF needed. 
And if done right ,you dont have to touch any setup you only change a CNAME.
Now lets say you move or setup a new webserver, all i change is web1.dom.tld and point that to a new server hostname. 
www.dom.tld CNAME web1.dom.tld  ( which is also a CNAME to sam-mem1.internal.domain.tld ) 

And yes you have to think in ahead here. 
So now for all serices configure the alias name, not the real hostname.

Kerberos works fine as long you A and PTR are the server is set. 
Certificates, per hostname and aliases where needed or in one certificate or multiple. 

This is also why i hammer on a correct DNS setup, if its not correct above will most probely fail. 

For windows, stop using \\hostname  start using \\hostname.internal.fqdn.tld 
Same user/profile shares use : 

Why not \\fs1.int.dom.tld\home\%username% or \\fs1.int.dom.tld\homes\%username% 
Well, one is really wrong and the other should work like \users\ but easy to make a mistake here. 
man smb.conf tells it all ;-)  

Tip for today.
