Correct me if I'm wrong Andrew, but I think Andrew is not
thinking about removing NTLM, but only the storage of
LM password hashes.

 From the "lanman auth" section of the man page:

This parameter has been deprecated since Samba 4.11 and
support for LanMan (as distinct from NTLM, NTLMv2 or Kerberos
authentication) will be removed in a future Samba release.

Removing the LM password hashes gets a hearty thumbs-up
from me :-).

But I may be miss-reading the original message. Sorry
if I'm just adding to the confusion :-).
