+    <para>
+    If a client connects to smbd using an untrusted domain name, such as
+    BOGUS\user, smbd replaces the BOGUS domain with it's SAM name before
+    attempting to authenticate that user.  In the case where smbd is acting as
+    a PDC this will be DOMAIN\user.  In the case where smbd is acting as a
+    domain member server or a standalone server this will be WORKSTATION\user.
+    </para>
+
+    <para>
+    In previous versions of Samba (pre 3.4), if smbd was acting as a domain
+    member server, the BOGUS domain name would instead be replaced by the
+    primary domain which smbd was a member of.  In this case authentication
+    would be deferred off to a DC using the credentials DOMAIN\user.
+    </para>
+
+    <para>
+    When this parameter is set to <constant>yes</constant> smbd provides the
+    legacy behavior of mapping untrusted domain names to the primary domain.
+    When smbd is not acting as a domain member server, this parameter has no
+    effect.
