<para>This parameter determines whether or not <citerefentry><refentrytitle>smbd</refentrytitle>
|
|
<manvolnum>8</manvolnum></citerefentry> 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.</para>
|
|
|
|
<para>The LANMAN encrypted response is easily broken, due to its
|
|
case-insensitive nature, and the choice of algorithm. Servers
|
|
without Windows 95/98/ME or MS DOS clients are advised to disable
|
|
this option. </para>
|
|
|
|
<para>When this parameter is set to <value>no</value> this
|
|
will also result in sambaLMPassword in Samba's passdb being
|
|
blanked after the next password change. As a result of that
|
|
lanman clients won't be able to authenticate, even if lanman
|
|
auth is re-enabled later on.
|
|
</para>
|
|
|
|
<para>Unlike the <command moreinfo="none">encrypt
|
|
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
|
|
special configuration to use it.</para>
