samba - Dec 2017 - [Curiosity] 'netbios aliases' works in AD mode?

Simply: i was (ab)used to have, in my NT domain, some aliases for my
servers, so i can change servers (and move services) but keeping things
consistent.

Eg, all my printers are connected to \\CUPS\\<printername>, and my main
share is \\FILE\Work . Ever.
Because 'CUPS' and 'FILE' are aliases of my servers.


Some weeks ago i've asked if samba in AD mode can have server aliases,
as 'netbios aliases' had in NT mode.

Someone (Andrew,
https://lists.samba.org/archive/samba/2017-December/212597.html)
reply me, 'yes', you have to set 'netbios aliases' but also add
'SPN'.


I'm simply trying to figure out how to do that, and i'm simply noted
that there's no DNS record for the aliases, as expected (ok, at least
as i expect ;).


I hope i'm clear, now.

OK, NT4-style domains use netbios to find computers.
    AD domains use dns
So, my advice would be to use CNAME records in AD.

What Andrew said was correct, but netbios is on the way out, it relies
on SMB1 and the latest Win10 has this turned off by default.

Ok, trying to sumarize: if i need a server alias:

a) for older clients (netbios/SMB1), i have to add 'netbios aliases'
 *AND* define SPN

b) for newer clients (AD/smb>1), i have to set a CNAME.


So, if i need both (for compatibility reason), i have to do both. Right?

Only b is needed. 

Im connecting here from a win 10 to a samba 3.6.6 smb1 through an CNAME.
