7 <para>This parameter determines whether or not <citerefentry><refentrytitle>smbclient</refentrytitle>
8 <manvolnum>8</manvolnum></citerefentry> will attempt to
9 authenticate itself to servers using the NTLMv2 encrypted password
12 <para>If enabled, only an NTLMv2 and LMv2 response (both much more
13 secure than earlier versions) will be sent. Older servers
14 (including NT4 < SP4, Win9x and Samba 2.2) are not compatible with
15 NTLMv2 when not in an NTLMv2 supporting domain</para>
17 <para>Similarly, if enabled, NTLMv1, <command
18 moreinfo="none">client lanman auth</command> and <command
19 moreinfo="none">client plaintext auth</command>
20 authentication will be disabled. This also disables share-level
21 authentication. </para>
23 <para>If disabled, an NTLM response (and possibly a LANMAN response)
24 will be sent by the client, depending on the value of <command
25 moreinfo="none">client lanman auth</command>. </para>
27 <para>Note that Windows Vista and later versions already use
28 NTLMv2 by default, and some sites (particularly those following
29 'best practice' security polices) only allow NTLMv2 responses, and
30 not the weaker LM or NTLM.</para>
