+<samba:parameter name="client use spnego principal"

+<description>
+ <para>This parameter determines whether or not
+ <citerefentry><refentrytitle>smbclient</refentrytitle>
+ <manvolnum>8</manvolnum></citerefentry> and other samba components
+ acting as a client will attempt to use the server-supplied
+ principal sometimes given in the SPNEGO exchange.</para>
+
+ <para>If enabled, Samba can attempt to use Kerberos to contact
+ servers known only by IP address. Kerberos relies on names, so
+ ordinarily cannot function in this situation. </para>
+
+ <para>This is a VERY BAD IDEA for security reasons, and so this
+ parameter SHOULD NOT BE USED. It will be removed in a future
+ version of Samba.</para>
+
+ <para>If disabled, Samba will use the name used to look up the
+ server when asking the KDC for a ticket. This avoids situations
+ where a server may impersonate another, soliciting authentication
+ as one principal while being known on the network as another.
+ </para>
+
+ <para>Note that Windows XP SP2 and later versions already follow
+ this behaviour, and Windows Vista and later servers no longer
+ supply this 'rfc4178 hint' principal on the server side.</para>
+
+ <para>This parameter is deprecated in Samba 4.2.1 and will be removed
+ (along with the functionality) in a later release of Samba.</para>
