I just added an SPN to a computer:

samba-tool spn add  'http/test.example.com.lan' 'myserver$'

But I don't see the name resolving through DNS:

host test.example.com
Host test.example.com not found: 3(NXDOMAIN)

While I agree an SPN is quite handy especially for kerberos 
authentication, it looks like it does not do anything to allow resolving 
the host by SPN-name / cname. If you ask me it is still necessary to add 
a cname record to DNS.
