No, the point is.. 

User verfications 
Computer verification
And Authentication. 
These are 3 different things. 

The differences, in terms. 
NTLM KERBEROS DNS-lookups and how this all works together. 

But i only type with lots of errors, this is better to read ;-) 

I cant hammer enough on.. 

A + PTR for the "real" registed server names. 
CNAME for aliasses.

So much relies on this these days. 
When its not perfect well, something "just" wont work. 

And i run exacty what you want.. 
I have 3 separated domains. 
A samba NT4DOM (3.6.X) 
A Samba AD DOM  4.12.6 
A Windows 2008R2 

All my pcs and user login against the samba AD
All other re-uses the user/passwords from the AD login. 

And i dont change registry keys to "make things work".. 
All defaults in the clients except what i push with GPO's. 

You know what you need todo.. Make it perfect again. 
Because in computer good is not good enough.. 

You want perfect, or as close you can be to perfect.
