+        pass
+
+    @abc.abstractmethod
+    def authenticate(self, context, auth_payload, auth_context):
+        """Authenticate user and return an authentication context.
+
+        :param context: keystone's request context
+        :param auth_payload: the content of the authentication for a given
+                             method
+        :param auth_context: user authentication context, a dictionary shared
+                             by all plugins. It contains "method_names" and
+                             "extras" by default. "method_names" is a list and
+                             "extras" is a dictionary.
+
+        If successful, plugin must set ``user_id`` in ``auth_context``.
+        ``method_name`` is used to convey any additional authentication methods
+        in case authentication is for re-scoping. For example, if the
+        authentication is for re-scoping, plugin must append the previous
+        method names into ``method_names``. Also, plugin may add any additional
+        information into ``extras``. Anything in ``extras`` will be conveyed in
+        the token's ``extras`` attribute. Here's an example of ``auth_context``
+        on successful authentication::
+
+            {
+                "extras": {},
+                "methods": [
+                    "password",
+                    "token"
+                ],
+                "user_id": "abc123"
+            }
+
+        Plugins are invoked in the order in which they are specified in the
+        ``methods`` attribute of the ``identity`` object. For example,
+        ``custom-plugin`` is invoked before ``password``, which is invoked
+        before ``token`` in the following authentication request::
+
+            {
+                "auth": {
+                    "identity": {
+                        "custom-plugin": {
+                            "custom-data": "sdfdfsfsfsdfsf"
+                        },
+                        "methods": [
+                            "custom-plugin",
+                            "password",
+                            "token"
+                        ],
+                        "password": {
+                            "user": {
+                                "id": "s23sfad1",

+                            }
+                        },

+                        }
+                    }
