ndg-oauth-server 0.5.1

OAuth 2.0 server

This is an OAuth 2.0 server library and WSGI middleware filter.

It supports simple string-based bearer token and a custom extension to enable
the use of X.509 certificates as tokens. The latter has been added for a
specialised use case to enable a SLCS (Short-lived Credential Service) to issue
delegated X.509-based credentials with OAuth.

Releases
========
0.5.1
-----
Integrated enhancements from Willem van Engen including:

* password-based client authentication, which is a commonly used client
authentication method
* resource authentication for the check_token endpoint, to avoid brute-force
attacks on token check; also provides a starting point for audience-restricted
tokens and resource-restricted attribute release
* return user attribute from check_token endpoint, so that the resource knows
what the user is; attribute name user_name according to CloudFoundry

Resource and client authentication use the same classes, and now are instantiated
with a string indicating their use (to give meaningful log messages). The
client_authenticator interface was removed, since all authenticators can derive
directly from authenticator_interface, since they're both used for clients and
resources; they were also renamed to make that clear (removing _client).

In client_register.ini and resource_register.ini (the latter is new) the field
secret is optional.

Client code is unchanged.

0.4.0
-----
* Revised examples in ndg.oauth.client.examples. bearer_tok uses bearer token
to secure access to a simple html page on a resource server, slcs is an
example protecting a short-lived credential service aka. Online Certificate
Authority. This requires the ContrailOnlineCAService package and should be
used in conjunction with the equivalent example in the ndg_oauth_client
example.
* Added discrete WSGI resource server middleware
ndg.oauth.server.wsgi.resource_server.Oauth2ResourceServerMiddleware
* Includes support for bearer access token passed in Authorization header to
resource server.

Prerequisites

bearer_tok/:
This configures a simple test application that uses string based tokens.
slcs/:
Bearer token example protecting a Short-Lived Credential Service or OnlineCA.
ContrailOnlineCAService package is needed for this example.
