<listitem>
<para>This parameter determines whether or not <citerefentry><refentrytitle>smbclient</refentrytitle>
<manvolnum>8</manvolnum></citerefentry> and other samba client
tools will attempt to authenticate itself to servers using the
weaker LANMAN password hash. If disabled, only server which support NT
password hashes (e.g. Windows NT/2000, Samba, etc... but not
Windows 95/98) will be able to be connected from the Samba client.</para>
<para>The LANMAN encrypted response is easily broken, due to it's
case-insensitive nature, and the choice of algorithm. Clients
without Windows 95/98 servers are advised to disable
this option. </para>
<para>Disabling this option will also disable the <command
moreinfo="none">client plaintext auth</command> option</para>
<para>Likewise, if the <command moreinfo="none">cleint ntlmv2
auth</command> parameter is enabled, then only NTLMv2 logins will be
attempted. Not all servers support NTLMv2, and most will require
special configuration to us it.</para>
<para>Default : <command moreinfo="none">client lanman auth = yes</command></para>

authenticate itself to servers using the NTLMv2 encrypted password
response.</para>
<para>If enabled, only an NTLMv2 and LMv2 response (both much more
secure than earlier versions) will be sent. Many servers
(including NT4 &lt; SP4, Win9x and Samba 2.2) are not compatible with
NTLMv2. </para>
<para>If disabled, an NTLM response (and possibly a LANMAN response)
will be sent by the client, depending on the value of <command
moreinfo="none">client lanman auth</command>. </para>
<para>Note that some sites (particularly
those following 'best practice' security polices) only allow NTLMv2
responses, and not the weaker LM or NTLM.</para>
