This parameter determines whether or not smbd 8 will attempt to authenticate users or permit password changes using the LANMAN password hash. If disabled, only clients which support NT password hashes (e.g. Windows NT/2000 clients, smbclient, but not Windows 95/98 or the MS DOS network client) will be able to connect to the Samba host. The LANMAN encrypted response is easily broken, due to it's case-insensitive nature, and the choice of algorithm. Servers without Windows 95/98/ME or MS DOS clients are advised to disable this option. Unlike the encrypt passwords option, this parameter cannot alter client behaviour, and the LANMAN response will still be sent over the network. See the client lanman auth to disable this for Samba's clients (such as smbclient) If this option, and ntlm auth are both disabled, then only NTLMv2 logins will be permited. Not all clients support NTLMv2, and most will require special configuration to use it. yes
