+
+On the client side, it provides a client that can authenticate to an SPNEGO
+Kerberos authenticated web service, and the ability to change client's
+password.
+
+On the server side, the library provides a HTTP handler wrapper implements
+SPNEGO Kerberos authentication, as well as a HTTP handler wrapper decodes
+Microsoft AD PAC authorization data.")
