However, this would not prevent the client from attempting to negotiate lanman
auth, or the server from accepting them; it would just mean that the client
would be denied access. Depending on where your security concerns lie
(sniffing vs. brute-forcing), removing the LanMan passwords from the smbpasswd
database may not provide any security improvement.
