   Note that, in particular, NTLM version 2 is not supported.
 
+  \section1 Options
+
+  In addition to the username and password required for authentication, a
+  QAuthenticator object can also contain additional options. The
+  options() function can be used to query incoming options sent by
+  the server; the setOption() function can
+  be used to set outgoing options, to be processed by the authenticator
+  calculation. The options accepted and provided depend on the authentication
+  type (see method()).
+
+  The following tables list known incoming options as well as accepted
+  outgoing options. The list of incoming options is not exhaustive, since
+  servers may include additional information at any time. The list of
+  outgoing options is exhaustive, however, and no unknown options will be
+  treated or sent back to the server.
+
+  \section2 Basic
+
+  \table
+    \header \o Option \o Direction \o Description
+    \row \o \tt{realm} \o Incoming \o Contains the realm of the authentication, the same as realm()
+  \endtable
+
+  The Basic authentication mechanism supports no outgoing options.
+
+  \section2 NTLM version 1
+
+  The NTLM authentication mechanism currently supports no incoming or outgoing options.
+
+  \section2 Digest-MD5

+  \table
+    \header \o Option \o Direction \o Description
+    \row \o \tt{realm} \o Incoming \o Contains the realm of the authentication, the same as realm()
