+        Ordinarily, when an application offers both "username/password
+        authentication" and "no authentication" to Tor via SOCKS5, Tor
+        selects username/password authentication so that IsolateSOCKSAuth can
+        work.  This can confuse some applications, if they offer a
+        username/password combination then get confused when asked for
+        one. You can disable this behavior, so that Tor will select "No
+        authentication" when IsolateSOCKSAuth is disabled, or when this
+        option is set.
