+ Specifies the channel binding type to use with SCRAM authentication.
+ The list of channel binding types supported by server are listed in
+ <xref linkend="sasl-authentication"/>. An empty value specifies that
+ the client will not use channel binding. The default value is
+ <literal>tls-unique</literal>.
+ </para>
+
+ <para>
+ Channel binding is only supported on SSL connections. If the
+ connection is not using SSL, then this setting is ignored.
+ </para>
+
+ <para>
+ This parameter is mainly intended for protocol testing. In normal
+ use, there should not be a need to choose a channel binding type other
+ than the default one.
