7 <para>This parameter determines whether or not
8 <citerefentry><refentrytitle>smbclient</refentrytitle>
9 <manvolnum>8</manvolnum></citerefentry> and other samba components
10 acting as a client will attempt to use the server-supplied
11 principal sometimes given in the SPNEGO exchange.</para>
13 <para>If enabled, Samba can attempt to use Kerberos to contact
14 servers known only by IP address. Kerberos relies on names, so
15 ordinarily cannot function in this situation. </para>
17 <para>If disabled, Samba will use the name used to look up the
18 server when asking the KDC for a ticket. This avoids situations
19 where a server may impersonate another, soliciting authentication
20 as one principal while being known on the network as another.
23 <para>Note that Windows XP SP2 and later versions already follow
24 this behaviour, and Windows Vista and later servers no longer
25 supply this 'rfc4178 hint' principal on the server side.</para>
