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.</para>

<para > The LANMAN encrypted response is easily broken, due to it's
case-insensitive nature, and the choice of algorithm. Servers
2004-12-23 05:18:53 +03:00
without Windows 95/98/ME or MS DOS clients are advised to disable
2004-04-07 14:15:11 +04:00
this option. </para>
<para > Unlike the <command moreinfo= "none" > encypt
passwords</command> option, this parameter cannot alter client
behaviour, and the LANMAN response will still be sent over the
network. See the <command moreinfo= "none" > client lanman
auth</command> to disable this for Samba's clients (such as smbclient)</para>
<para > If this option, and <command moreinfo= "none" > ntlm
auth</command> are both disabled, then only NTLMv2 logins will be
permited. Not all clients support NTLMv2, and most will require
2004-12-23 05:18:53 +03:00
special configuration to use it.</para>
