+    Privoxy itself does not support proxy authentication, but can
+    allow clients to authenticate against Privoxy's parent proxy.
+   </para>
+   <para>
+    By default Privoxy (3.0.21 and later) don't do that and remove
+    Proxy-Authorization headers in requests and Proxy-Authenticate
+    headers in responses to make it harder for malicious sites to
+    trick inexperienced users into providing login information.
+   </para>
+   <para>
+    If this option is enabled the headers are forwarded.
+   </para>
+   <para>
+    Enabling this option is <emphasis>not recommended</emphasis> if there is
+    no parent proxy that requires authentication or if the local network between
+    Privoxy and the parent proxy isn't trustworthy. If proxy authentication is
+    only required for some requests, it is recommended to use a client header filter
+    to remove the authentication headers for requests where they aren't needed.
